2.5.1 Stand-AloneOperation

When used as a stand-aloneEVM, power isappliedtoP23/J23directly,making suretoreferencethe suppliestotheappropriategroundson thatconnector. CAUTION Verifythatallpower suppliesarewithinthesafeoperatinglimitsshown on the TLV320AIC3204 datasheetbeforeapplyingpower totheEVM. P23/J23providesconnectiontothecommon power bus fortheTLV320AIC3204EVM. Power issupplied on thepinslistedinTable6. The TLV320AIC3204EVM-K motherboard(theUSB-MODEVM Interfaceboard)suppliespower toP23/J23 oftheTLV320AIC3204EVM. Power forthemotherboardissuppliedeitherthroughitsUSB connectionor viaterminalblockson thatboard.

2.5.2 USB-MODEVM Operation

The USB-MODEVM Interfaceboardcan be powered fromseveraldifferentsources:

USB
6-Vdcto10-VdcAC/DC externalwallsupply(notincluded)
Laboratorypower supply When powered fromtheUSB connection,JMP6 must have a shuntfrompins1–2 (thisisthedefault factoryconfiguration).When powered from6-Vdcto10-Vdcpower supply,eitherthroughtheJ8 terminal blockorJ9 barreljack,JMP6 must have a shuntinstalledon pins2–3.Ifpower isappliedinany ofthese ways,onboardregulatorsgeneratetherequiredsupplyvoltages,and no furtherpower suppliesare necessary. Iflaboratorysuppliesareused toprovidetheindividualvoltagesrequiredby theUSB-MODEVM Interface, JMP6 must have no shuntinstalled.VoltagesarethenappliedtoJ2 (+5VA),J3 (+5VD),J4 (+1.8VD),and J5 (+3.3VD).The +1.8VD and +3.3VD can alsobe generatedon theboardby theonboardregulatorsfrom the+5VD supply;toenablethisconfiguration,theswitcheson SW1 need tobe settoenablethe regulatorsby placingthem intheON position(lowerposition,lookingattheboardwithtextreadingright- sideup).If+1.8VD and +3.3VD aresuppliedexternally,disabletheonboardregulatorsby placingSW1 switchesintheOFF position. Each power supplyvoltagehas an LED (D1-D7)thatilluminateswhen thepower suppliesareactive.

3.2 EVM Connections

EnsurethattheTLV320AIC3204EVM isinstalledon theUSB-MODEVM Interfaceboard,aligningJ11, J12,J21,J22,and J23 withthecorrespondingconnectorson theUSB-MODEVM. 2. Verifythatthejumpersand switchesareintheirdefaultconditions. 3. Attacha USB cablefromthePC totheUSB-MODEVM Interfaceboard.The defaultconfiguration providespower,controlsignals,and streamingaudioviatheUSB interfacefromthePC. On theUSB- MODEVM, LEDs D3, D4, D5, and D7 illuminatetoindicatethattheUSB issupplyingpower. 4. Forthefirstconnection,thePC recognizesnew hardwareand beginsan initializationprocess.The usermay be promptedtoidentifythelocationofthedriversorallowthePC toautomaticallysearchfor them.Allowtheautomaticdetectionoption. 5. Once thePC confirmsthatthehardwareisoperational,D2 on theUSB-MODEVM illuminatesto indicatethatthefirmwarehas been loadedand theEVM isreadyforuse.IfD2 does notilluminate, verifythattheEEPROM jumperand switchsettingsconformtoTable1 and Table2. AftertheTLV320AIC3204EVM-K softwareinstallation(describedinSection3.2)iscomplete,evaluation and developmentwiththeTLV320AIC3204 can begin.

The WaitforFlagcommand, f,readsa specifiedregisterand verifiesifthebitmapprovidedwiththe command matches thedatabeingread.Ifthedatadoes notmatch,thecommand handlerretriesforup to 200 times.Thisfeatureisusefulwhen switchingbuffersinpartsthatsupporttheadaptivefilteringmode. The command fsyntaxfollows: f[i2caddress][register][D7][D6][D5][D4][D3][D2][D1][D0]where'i2caddress'and'register' areinhexadecimalformatand'D7'through'D0'areinbinaryformatwithvaluesof0,1orXfor don'tcare.

Each bytevalueisexpressedin hexadecimal,and each bytemust be separatedby a space.Commands areinterpretedand senttothe TAS1020B by theprogramusingtheprotocoldescribedinSectionG.1. The firstbytefollowingan r(read)orw (write)command istheI2C slaveaddressofthedevice(ifI2C is used)orthefirstdatabytetowrite(ifSPI isused— notethatSPI interfacesarenotstandardizedon protocols,so themeaning ofthisbytevarieswiththedevicebeingaddressedon theSPI bus).The second byteisthestartingregisteraddressthatdatawillbe writtento(again,withI2C; SPI varies— see SectionG.1 foradditionalinformationaboutwhat variationsmay be necessaryfora particularSPI mode).
