3.2 Power Considerations

The VCE6467T providesseveralmeans ofmanaging power consumption. As describedintheSection6.3.4,VCE6467T Power and ClockDomains,theVCE6467T has one single power domain— the “Always On ” power domain.Withinthispower domain,theVCE6467T utilizeslocal clockgatingviathePower and SleepController(PSC) toachievepower savings.For more detailson the PSC, see Section6.3.5, Power and Sleep Controller(PSC) and the TMS320DM646x DMSoC ARM Subsystem ReferenceGuide (literaturenumber SPRUEP9 ). Some oftheVCE6467T peripheralssupportadditionalpower savingfeatures.For more detailson power saving features supported, see the peripheral-specificreference guides [listed/linkedin the TMS320DM646x DMSoC PeripheralsOverviewReferenceGuide (literaturenumber SPRUEQ0 ). Most VCE6467T 3.3-VI/Oscan be powered-down toreducepower consumption.The VDD3P3V_PWDN registerintheSystem Module (seeFigure3-1)isused toselectivelypower down unused 3.3-VI/Opins. Note:To save power,allotherI/Obuffersarepowered down by default.Beforeusingthesepins,theuser must programtheVDD3P3V_PWDN registertopower up thecorrespondingI/Obuffers. For a listofmultiplexedpinson thedeviceand thepinmux groupeach pinbelongsto,see Section3.7.3, PinMultiplexingDetails. Note: The VDD3P3V_PWDN registeronlycontrolsthe power to the I/Obuffers.The Power and Sleep Controller(PSC) determinestheclock/powerstateoftheperipheral. 31 29 28 27 26 25 24 23 22 21 20 19 18 17 16 RESERVED USBV CLKOUT RSV SPI VLYNQ RESERVED GMII MII MCASP1 MCASP0 PCIHPI1 PCIHPI0 R-000 R/W-1 R/W-0 R-0 R/W-1 R/W-1 R-00 R/W-1 R/W-1 R/W-1 R/W-1 R/W-0 R/W-0 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 GPIO WDTIM TIM23 TIM01 PWM1 PWM0 UR2FC UR2DAT UR1FC UR1DAT UR0MDM UR0DF VPIF3 VPIF2 VPIF1 VPIF0 R/W-0 R/W-0 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-1 R/W-0 R/W-1 R/W-1 LEGEND: R/W = Read/Write;R = Read only;-n = valueafterreset Figure3-1.VDD3P3V_PWDN Register[0x01C4 0048] Copyright© 2011,Texas InstrumentsIncorporated DeviceConfigurations 85 SubmitDocumentationFeedback ProductFolderLink(s):VCE6467T AVCE6467T

3.4 Boot Sequence

The bootsequence isa processby whichthedevice'smemory isloadedwithprogram and datasections, and by whichsome ofthedevice'sinternalregistersareprogrammed withpredeterminedvalues.The boot sequence isstartedautomaticallyaftereach device-levelglobalreset.For more detailson device-level globalresets,see Section6.7,Reset. There areseveralmethods by whichthememory and registerinitializationcan takeplace.Each ofthese methods is referredto as a boot mode. The boot mode to be used is selectedat reset.For more informationon thebootmode selections,see Section3.4.1,BootModes . The deviceisbooted throughmultiplemeans — primarybootloaderswithininternalROM or EMIFA, and secondaryuserbootloadersfrom peripheralsor externalmemories.Boot modes, pinconfigurations,and registerconfigurationsrequiredforbootingthedevice,aredescribedinthefollowingsubsections.

3.4.1 Boot Modes

The VCE6467T bootmodes aredeterminedby thesedevicebootand configurationpins.For information on how thesepinsare sampled at devicereset,see Section6.7.1.2, LatchingBoot and Configuration Pins.

BTMODE[3:0]

CS2BW
DSPBOOT The TMS320DM646x DMSoC ARM can boot eitherfrom asynchronousEMIF/NOR Flashor from ARM ROM, as determinedby thedevicebootand configurationpinsatreset(BTMODE[3:0] and PCIEN). The PCIEN pinconfigurationisused to selectthe defaultconfigurationof the EMIFA/PCI/HPI pinsat reset. This allowsthe DM646xT DMSoC to be PCI-compliantat reset.When PCIEN = 1, the PCI module controlsthemultiplexedpinswiththeappropriatepullup/pulldownconfiguration.For allotherbootmodes (non-PCIbootmodes),thePCIEN must be clearedto"0". For a more detaileddescriptionoftheROM bootmodes supportedby theDM646xT DMSoC, see Using theTMS320DM646x BootloaderApplicationReport(literaturenumber SPRAAS0 ).

Under thisscenario(DSPBOOT = 0),the DSP will remaindisabled(heldinreset)afterreset.The ARM isresponsibleforreleasingDSP from reset.Before releasingDSP fromreset,theARM must transfera validDSP bootimage toprogram memory accessible by theDSP (DSP memory, EMIFA or DDR2), and configuretheDSP bootaddressinDSPBOOTADDR register(inSYSTEM module)fromwhichtheDSP willbeginexecution. When DSPBOOT = 1, the DSP willboot itself.Under thisscenario,DSP willbe releasedfrom reset withoutARM intervention.The DSP boot addressissetto an EMIFA address0x4220 0000h. DSP will beginexecutionwithinstruction(L1P)cache enabled. Note: The DSPBOOT operationisoverriddenwhen ARM HPI or PCI bootisselected(BTMODE[3:0] = 001x).Thisisbecause ARM HPI/PCIbootselectionwillforcetheHPIEN orPCIEN bitinPINMUX0 to‘1’. ThisenablesUHPI/PCI functionson theEMIFA controland datapinsand preventstheDSP from using EMIFA.

3.8 Debugging Considerations

3.8.1 Pullup/PulldownResistors

ProperboarddesignshouldensurethatinputpinstotheTMS320DM646x DMSoC devicealwaysbe ata validlogicleveland notfloating.Thismay be achievedviapullup/pulldownresistors.The TMS320DM646x DMSoC featuresinternalpullup(IPU)and internalpulldown(IPD)resistorson most pinstoeliminatethe need,unlessotherwisenoted,forexternalpullup/pulldownresistors. An externalpullup/pulldownresistorneeds tobe used inthefollowingsituations:

Boot and ConfigurationPins: Ifthe pin is both routedout and 3-stated(notdriven),an external pullup/pulldownresistoris strongly recommended , even ifthe IPU/IPD matches the desired value/state.
Other Input Pins: If the IPU/IPD does not match the desired value/state,use an external pullup/pulldownresistortopullthesignaltotheoppositerail. For thebootand configurationpins(listedinTable2-6,Boot TerminalFunctions),iftheyarebothrouted out and 3-stated(notdriven),itisstronglyrecommended thatan externalpullup/pulldownresistorbe implemented.Although,internalpullup/pulldownresistorsexiston thesepinsand theymay match the desiredconfigurationvalue,providingexternalconnectivitycan help ensure thatvalidlogiclevelsare latchedon these device boot and configurationpins.In addition,applyingexternalpullup/pulldown resistorson thebootand configurationpinsadds conveniencetotheuserindebuggingand flexibilityin switchingoperatingmodes. Tipsforchoosingan externalpullup/pulldownresistor:
Considerthetotalamount ofcurrentthatmay pass throughthepulluporpulldownresistor.Make sure toincludetheleakagecurrentsofallthedevicesconnectedtothenet,as wellas any internalpullupor pulldownresistors.
Decidea targetvalueforthenet.For a pulldownresistor,thisshouldbe below thelowestVIL levelof allinputsconnectedtothenet.For a pullupresistor,thisshouldbe above thehighestVIH levelofall inputson thenet.A reasonablechoicewould be totargettheVOL orVOH levelsforthelogicfamilyof thelimitingdevice;which,by definition,have margintotheVIL and VIH levels.
Selecta pullup/pulldownresistorwiththelargestpossiblevalue;but,whichcan stillensurethatthenet willreachthetargetpulledvaluewhen maximum currentfromalldeviceson thenetisflowingthrough the resistor.The currentto be consideredincludesleakage currentplus,any otherinternaland externalpullup/pulldownresistorson thenet.
For bidirectionalnets,thereisan additionalconsiderationwhich setsa lowerlimiton the resistance valueoftheexternalresistor.Verifythattheresistanceissmallenough thattheweakestoutputbuffer can drivethenettotheoppositelogiclevel(includingmargin).
Remember toincludetoleranceswhen selectingtheresistorvalue.
Forpullupresistors,alsoremember toincludetoleranceson theDV DD rail. For most systems,a 1-kΩ resistorcan be used tooppose theIPU/IPDwhilemeetingtheabove criteria.

6.3 Power Supplies

For more informationregardingTI'spower management productsand suggesteddevicesto power TI DSPs, visitwww.ti.com/processorpower.

6.3.1 Power-Supply Sequencing

The VCE6467T includesone coresupply(CVDD ),and two I/Osupplies— DV DD33 and DV DDR2 .To ensure properdeviceoperation,a specificpower-upsequence must be followed.Some TIpower-supplydevices includefeaturesthat facilitatepower sequencing— for example, Auto-Trackand Slow-Start/Enable features.Formore informationon TIpower suppliesand theirfeatures,visitwww.ti.com/processorpower. Here isa summary ofthepower sequencingrequirements:

The power ramp ordermust be CV DD beforeDV DDR2 , and DV DDR2 beforeDV DD33 — meaning during power up,thevoltageattheDV DDR2 railshouldneverexceed thevoltageattheCV DD rail.Similarly, thevoltageattheDV DDD33 railshouldneverexceed thevoltageattheDV DDR2 rail.
From the timethatpower ramp begins,allpower supplies(CVDD , DV DDR2 , DV DD33 ) must be stable within200 ms. The term "stable"means reachingthe recommended operatingcondition(see Section5.2,Recommended OperatingConditionstable).

6.3.2 Power-Supply Design Considerations

Core and I/Osupplyvoltageregulatorsshouldbe locatedclosetotheDSP (orDSP array)tominimize inductanceand resistanceinthepower deliverypath.Additionally,when designingforhigh-performance applicationsutilizingtheVCE6467T device,thePC boardshouldincludeseparatepower planesforcore, I/O,and ground;allbypassedwithhigh-qualitylow-ESL/ESR capacitors.

6.3.3 Power-Supply Decoupling

Inordertoproperlydecouplethesupplyplanesfrom system noise,placeas many capacitors(caps)as possiblecloseto theVCE6467T. These caps need to be closeto theVCE6467T power pins,no more than 1.25 cm maximum distanceto be effective.Physicallysmallercaps,such as 0402, are betterbut need to be evaluated from a yield/manufacturingpoint-of-view.Parasiticinductancelimitsthe effectivenessof the decouplingcapacitors,thereforephysicallysmallercapacitorsshouldbe used while maintainingthelargestavailablecapacitancevalue. Largercaps foreach supplycan be placedfurtheraway forbulkdecoupling.Largebulkcaps (ontheorder of100 μF) shouldbe furthestaway, butstillas closeas possible.Large caps foreach supplyshouldbe placedoutsideoftheBGA footprint. As withtheselectionofany component,verificationofcapacitoravailabilityovertheproduct'sproduction lifetimeshouldbe considered. For more detailson capacitorusage and placement,see the ImplementingDDR2 PCB Layouton the TMS320DM646x DMSoC ApplicationReport(literaturenumber SPRAAM1A ).

6.3.4 VCE6467T Power and Clock Domains

The VCE6467T includesone singlepower domain — the"AlwaysOn" power domain.The "AlwaysOn" power domain isalwayson when thechipison.The "AlwaysOn" domain ispowered by theCV DD pinsof the VCE6467T. AllVCE6467T modules liewithinthe "AlwaysOn" power domain.Table 6-1 providesa listingoftheVCE6467T clockdomains. Two primaryreferenceclocksarerequiredfortheVCE6467T device.These can eitherbe crystalinputsor drivenby externaloscillators.A 33-MHz or33.3-MHz crystalisrecommended forthesystem PLLs,which generatethe internalclocksforthe ARM926, DSP, HDVICPs, peripherals,and the EDMA3. A 24- or 48-MHz crystalisalsorequirediftheUSB (24-MHz only)orUART (either24-or48-MHz) peripheralsare to be used.In addition,the 24- or 48-MHz inputclockcan be used to sourcethe McASPs' clocks.For furtherdescriptionoftheVCE6467T clockdomains,see and Figure6-4.

6.5 Clock PLLs

There aretwo independentlycontrolledPLLs on VCE6467T. PLL1 generatesthefrequenciesrequiredfor the ARM, DSP, HDVICP0/1, EDMA, and peripherals.PLL2 generatesthe frequenciesrequiredforthe DDR2 interface.Any inputcrystalfrequencybetween 27 MHz and 35 MHz can be used fortheSystem Oscillator(DEV_MXI/DEV_CLKIN). The recommended referenceclockforboth PLLs isthe 33-MHz or 33.3-MHz crystalinput.The VCE6467T has a thirdPLL thatisembedded withintheUSB2.0 PHY and the 24-MHz oscillatorisitsreferenceclocksource.ThisparticularPLL isonlyusableforUSB operation,and is discussedfurtherin the TMS320DM646x DMSoC UniversalSerialBus (USB) ControllerUser'sGuide (literaturenumber SPRUER7 ).

6.5.1 PLL1 and PLL2

Both PLL1 and PLL2 power aresuppliedexternallyviathe1.8-VPLL power-supplypins(PLL1VDD18 and PLL2V DD18 ).An externalEMI filtercircuitmust be added to PLL1V DD18 and PLL2V DD18 , as shown in Figure6-11.The 1.8-VsupplyoftheEMI filtersmust be fromthesame 1.8-Vpower planesupplyingthe device’s 1.8-V I/O power-supplypins (DVDDR2 ).TI recommends EMI filtermanufacturerMurata,part number NFM18CC222R1C3. AllPLL externalcomponents (C1,C2, C3, C4, and theEMI Filters)must be placedas closetothedevice as possible.For the bestperformance,TI recommends thatallthe PLL externalcomponents be on a singleside of the board withoutjumpers,switches,or components otherthan the ones shown in Figure6-11.For reducedPLL jitter,maximizethespacingbetween switchingsignalsand thePLL external components (C1,C2, C3, C4, and theEMI Filters). Figure6-11.PLL1 and PLL2 ExternalConnection The minimum CLKIN riseand falltimesshouldalsobe observed.For theinputclocktimingrequirements, see Section6.5.5,ClockPLL ElectricalData/Timing(Inputand OutputClocks). There isan allowablerange forPLL multiplier(PLLM). There isa minimum and maximum operating frequency for DEV_MXI/DEV_CLKIN, PLLOUT, AUX_MXI/AUX_CLKIN, and the device clocks (SYSCLKs). The PLL Controllersmust be configurednottoexceed any oftheseconstraintsdocumented in thissection(certaincombinationsof externalclockinputs,internaldividers,and PLL multiplyratios mightnotbe supported).Fortheseconstraints(ranges),see Table6-7through.

6.6 Enhanced DirectMemory Access (EDMA3) Controller

The EDMA controllerhandlesalldatatransfersbetween memories and thedeviceslaveperipheralson the VCE6467T device.These data transfersincludecache servicing,non-cacheablememory accesses, user-programmeddatatransfers,and hostaccesses.These aresummarized as follows:

Transferto/fromon-chipmemories – ARM926 TCM – DSP L1D memory – DSP L2 memory
Transferto/fromexternalstorage – DDR2 SDRAM – NAND flash – AsynchronousEMIF (EMIFA) – ATA
Transferto/fromperipherals/hosts – VLYNQ – HPI – McASP0/1 – SPI – I2C – PWM0/1 – UART0/1/2 – PCI The EDMA supportstwo addressingmodes: constantaddressingand incrementaddressing.On the VCE6467T, constantaddressingmode isnot supportedby any peripheralor internalmemory. For more informationon thesetwo addressingmodes, see theTMS320DM646x DMSoC Enhanced DirectMemory Access (EDMA) ControllerUser’s Guide (literaturenumber SPRUEQ5 ). The VCE6467T devicesupportsa programmabledefaultburstsizefeature.The defaultburstsizeofeach EDMA3 TransferController(TC) is configuredvia the EDMA TransferControllerDefaultBurstSize Configurationregister(EDMATCCFG). For more detailedinformationon theEDMATCCFG register,see Section3.6.2,PeripheralSelectionAfterDeviceReset.

6.6.1 EDMA3 Channel SynchronizationEvents

The EDMA supportsup to 64 EDMA channelswhich serviceperipheraldevicesand externalmemory. Table6-15 liststhesourceofEDMA synchronizationeventsassociatedwitheach oftheprogrammable EDMA channels.For theVCE6467T device,theassociationofan eventtoa channelisfixed;each ofthe EDMA channelshas one specificevent associatedwithit.These specificeventsare capturedin the EDMA eventregisters(ER, ERH) even ifthe eventsare disabledby the EDMA eventenableregisters (EER, EERH). For more detailedinformationon theEDMA module and how EDMA eventsare enabled, captured,processed,linked,chained,and cleared,etc.,see the TMS320DM646x DMSoC Enhanced DirectMemory Access (EDMA) ControllerUser’s Guide (literaturenumber SPRUEQ5 ) Table6-15.VCE6467T EDMA Channel SynchronizationEvents(1) EDMA EVENT NAME EVENT DESCRIPTIONCHANNEL 0-3 – Reserved (1) Inadditiontotheeventsshown inthistable,each ofthe64 channelscan alsobe synchronizedwith thetransfercompletionoralternatetransfercompletionevents.Formore detailedinformationon EDMA event-transferchaining,see theTMS320DM646x DMSoC Enhanced DirectMemory Access (EDMA) ControllerUser's Guide (literaturenumber SPRUEQ5 ).

Power-on Reset (POR) isinitiatedby thePOR pinand isused toresettheentirechip,includingthetest and emulationlogic.Power-on Reset isalsoreferredto as a coldresetsincethe deviceusuallygoes througha power-upcycle.Duringpower-up,thePOR pinmust be asserted(drivenlow)untilthepower supplieshave reached theirnormal operatingconditions.Ifan externaloscillatoris used on the DEV_MXI/DEV_CLKIN pin,the source clockshouldalsobe runningat the correctfrequencypriorto de-assertingthePOR pin.Note:A devicepower-upcycleisnotrequiredtoinitiatea Power-onReset. The followingsequence must be followedduringa Power-onReset. 1. Waitforthepower suppliestoreachnormaloperatingconditionswhilekeepingthePOR pinasserted (drivenlow). 2. Waitfortheinputclocksourcetobe stablewhilekeepingthePOR pinasserted(low). 3. Once thepower suppliesand theinputclocksourcearestable,thePOR pinmust remainasserted (low)fora minimum of12 DEV_MXI cycles. WithinthelowperiodofthePOR pin,thefollowinghappens: – The resetsignalsflowtotheentirechip(includingthetestand emulationlogic),resettingthe modules on chip. – The PLL ControllerclocksstartatthefrequencyoftheDEV_MXI clock.The clocksarepropagated throughoutthechiptoresetthechipsynchronously.By default,bothPLL1 and PLL2 areinreset and unlocked.The PLL ControllersdefaulttoPLL Bypass Mode. 4.

6.8 Interrupts

The VCE6467T devicehas a largenumber ofinterruptstoservicetheneeds ofitsmany peripheralsand subsystems.Both the ARM and C64x+ are capable of servicingthese interrupts.Allof the device interruptsare routedtotheARM interruptcontrollerwithonlya limitedsetroutedtotheC64x+ interrupt controller.The interruptscan be selectivelyenabled or disabledin eitherof the controllers.In typical applications,the ARM handles most of the peripheralinterruptsand grantscontrolto the C64x+ for interruptsthatarerelevanttoDSP algorithms.Also,theARM and DSP can communicate witheach other throughinterrupts.

6.8.1 ARM CPU Interrupts

The ARM926 CPU core supports2 directinterrupts:FIQ and IRQ. The VCE6467T ARM interrupt controllerprioritizesup to64 interruptrequestsfromvariousperipheralsand subsystems,whicharelisted inTable6-23,and interruptstheARM CPU. Each interruptisprogrammableforup to8 levelsofpriority. There are6 levelsforIRQ and 2 levelsforFIQ.Interruptsatthesame prioritylevelareservicedinorder by theARM InterruptNumber, withthelowestnumber havingthehighestpriority.Table6-24 shows the ARM interruptcontrollerregistersand memory locations.For more detailson ARM interruptcontrol,see theTMS320DM646x DMSoC ARM Subsystem ReferenceGuide (literaturenumber SPRUEP9 ).

6.11.2 VPIF Clock Control(Captureand Display)

The sourceclocksforthe VPIF data channelsare selectablebased on the settingsof the VIDCLKCTL register(0x01C4 0038) (Forthe VIDCLKCTL registerdetails,see Section3.3.2.1, Video Clock Control Register).The VSCLKDIS register(0x01C4 006C) isused todisabletheclockinputswhen changingthe clocksource to ensure glitch-freeoperation.(Forthe VSCLKDIS registerdetails,see Section3.3.2.3, Videoand TSIF ClockDisable). For boththeVPIF dual8-bitor16-bitvideo-capturemodes, Channel 0 isalwaysclockedby VP_CLKIN0 (seeFigure6-34). Figure6-34.VPIF Capture Channel 0 Source Clock Video-CaptureChannel 1 isclockedby the VP_CLKIN1 signal,when the dual 8-bitcapturemode is enabled.When the16-bitcapturemode or8-/10-/12-bitraw-capturemode isused,VP_CLKIN0 must be selectedas theclocksource(VIDCLKCTL.VCH1CLK = 0)[seeFigure6-35].

1-bitSerialand 8-bitParallelindependentreceiveand transmitinterfaceswithbothsynchronousand asynchronousmodes. (TSIF1 supportsSerialmode only.)
Stream input/output(I/O)speed rateconfigurableby theI/Oclockspeed
ATS (absolutetimestamp)detection,correction,and additionmodes
AutomaticallydetectsPAT and PMT and reflectsassignmenttotheinternalPacketIdentification(PID) table(supportedfor partialTransferStream [TS] mode only; stream type and PID should be one-to-onemapping)
PID filterwith7 PID filtertablesand streamtypeassignments
BYPASS mode implemented so thatnot only TS data,but any otherdata can be receivedor transmittedby theTSIF module
Ringbuffercontrolforbothwrites(8channels)and reads(1channel)to/frommemory
Supports“SpecificPacket”,indicatingboundaryofpluralprogramon TS
SupportsFull-TSinonlyone mode –Semi-Automatic-Amode, allowingcommunicationto the C64x+ CPU.
Supports Partial-TSin these modes –Semi-Automatic-Bmode and Full-Automaticmode (provided streamtypeand PID areone-to-onemapping) For more detailedinformationon the CRGEN peripheral,see the TMS320DM646x DMSoC Clock ReferenceGeneratorUser'sGuide (literaturenumber SPRUEQ1 ).

6.16 EthernetMAC (EMAC)

The EthernetMedia Access Controller(EMAC) module providesan efficientinterfacebetween the VCE6467T and thenetworkedcommunity.The EMAC supports10Base-T (10Mbits/second[Mbps]),and 100BaseTX (100 Mbps), ineitherhalf-or full-duplexmode, and 1000BaseT (1000 Mbps) infull-duplex mode, withhardwareflowcontroland quality-of-service(QOS) support. The EMAC controlstheflowofpacketdatafrom theVCE6467T devicetothePHY. The MDIO module controlsthePHY configurationand statusmonitoring. The EMAC module conformsto the IEEE 802.3-2002standard,describingthe “CarrierSense Multiple Access withCollisionDetection(CSMA/CD) Access Method and PhysicalLayer”specifications.The IEEE 802.3standardhas alsobeen adoptedby ISO/IECand re-designatedas ISO/IEC8802-3:2000(E). Deviatingfrom thisstandard,theEMAC module does notuse theTransmitCoding ErrorsignalMTXER. Insteadofdrivingtheerrorpinwhen an underflowconditionoccurson a transmittedframe,theEMAC will intentionallygeneratean incorrectchecksum by invertingthe frame CRC, so thatthe transmittedframe willbe detectedas an errorby the network.In addition,the EMAC I/Osoperateat 3.3 V and are not compatiblewith2.5-VI/Osignaling.Therefore,onlyEthernetPHYs with3.3-VI/Ointerfaceshouldbe used. Both the EMAC and MDIO modules interfaceto the VCE6467T devicethrougha custom interfacethat allowsefficientdatatransmissionand reception.Thiscustom interfaceisreferredtoas theEMAC control module. The EMAC controlmodule containsthe necessarycomponents to allowthe EMAC to make efficientuse ofdevicememory, plusitcontrolsdeviceinterrupts.The EMAC controlmodule incorporates 8K bytesofinternalRAM toholdEMAC bufferdescriptors. For more detailedinformationon the EMAC, see the TMS320DM646x DMSoC EthernetMedia Access Controller(EMAC)/Management Data Input/Output(MDIO) Module User's Guide (literaturenumber SPRUEQ6 ).

6.16.1 EMAC Device-SpecificInformation

The EMAC module on theVCE6467T supportstwo interfacemodes: Media IndependentInterface(MII) and GigabitMedia IndependentInterface(GMII).The MII and GMII interfacemodes are definedinthe IEEE 802.3-2002standard. The VCE6467T EMAC uses thesame pinsfortheMIIand GMII modes ofoperation.Only one mode can be used at a time.The mode used is selectedat device resetbased on the GMIIEN bitin the MACCONTROL register.For more detailedinformationon the EMAC GMIIEN bit,see the TMS320DM646x DMSoC EthernetMedia Access Controller(EMAC)/Management Data Input/Output (MDIO) Module User'sGuide (literaturenumber SPRUEQ6 ). The MIIand GMII modes-of-operationpinsareas follows:

MII:MTCLK, MRCLK, MTXD[3:0],MRXD[3:0],MTXEN, MRXDV, MRXER, MCOL, MCRS, MDCLK, and MDIO.
GMII: RFTCLK, GMTCLK, MTCLK, MRCLK, MTXD[7:0],MRXD[7:0], MTXEN, MRXDV, MRXER, MCOL, MCRS, MDCLK, and MDIO.

6.17 Management Data Input/Output(MDIO)

The Management Data Input/Output(MDIO) module continuouslypollsall32 MDIO addressesinorderto enumerateallPHY devicesinthesystem. The Management Data Input/Output(MDIO) module implementsthe802.3serialmanagement interfaceto interrogateand controlEthernetPHY(s) usinga shared two-wirebus. Host softwareuses the MDIO module to configurethe auto-negotiationparametersof each PHY attachedto the EMAC, retrievethe negotiationresults,and configurerequiredparametersinthe EMAC module forcorrectoperation.The module is designed to allow almost transparentoperationof the MDIO interface,with very little maintenancefromthecoreprocessor.Onlyone PHY may be connectedatany giventime. For more detailedinformationon theMDIO peripheral,see theTMS320DM646x DMSoC EthernetMedia Access Controller(EMAC)/Management Data Input/Output(MDIO) Module User's Guide (literature number SPRUEQ6 ).For a listofsupportedregistersand registerfields,see Table6-78,MDIO Registers inthisdatamanual.

6.22 MultichannelAudio SerialPort(McASP0/1) Peripherals

The multichannelaudioserialport(McASP) functionsas a general-purposeaudioserialportoptimizedfor the needs of multichannelaudioapplications.The McASP isusefulfortime-divisionmultiplexed(TDM) stream,Inter-IntegratedSound (I2S)protocols,and intercomponentdigitalaudiointerfacetransmission (DIT).

6.22.1 McASP Device-SpecificInformation

The VCE6467T device includestwo multichannelaudio serialport (McASP) interfaceperipherals (McASP0 and McASP1). The McASP0 module consistsofa transmitand receivesection.These sections can operatecompletelyindependentlywithdifferentdataformats,separatemasterclocks,bitclocks,and framesyncsoralternatively,thetransmitand receivesectionsmay be synchronized.The McASP0 module alsoincludesa pool of 4 shiftregistersthatmay be configuredto operateas eithertransmitdata or receivedata. The transmitsectionof the McASP0 can transmitdata in eithera time-division-multiplexed(TDM) synchronousserialformator ina digitalaudiointerface(DIT)formatwhere thebitstreamisencoded for S/PDIF,AES-3, IEC-60958,CP-430 transmission.The receivesectionoftheMcASP0 peripheralsupports theTDM synchronousserialformat. The McASP0 module can supportone transmitdataformat(eithera TDM formatorDIT format)and one receiveformatata time.Alltransmitshiftregistersuse thesame formatand allreceiveshiftregistersuse thesame format.However,thetransmitand receiveformatsneed notbe thesame. Both thetransmitand receivesectionsoftheMcASP alsosupportburstmode which isusefulfornon-audiodata(forexample, passingcontrolinformationbetween two DSPs). The McASP0 peripheralhas additionalcapabilityfor flexibleclock generation,and error detection/handling,as wellas errormanagement. The VCE6467T McASP1 module isa reduced featureversionof the McASP peripheral.The McASP1 module providesa singletransmit-onlyshiftregisterand can transmitdatainDIT formatonly. For more detailedinformationon and thefunctionalityoftheMcASP peripheral,see theTMS320DM646x DMSoC MultichannelAudioSerialPort(McASP) User'sGuide (literaturenumber SPRUER1 ).
