Pin Description -CE1, -CE2 (PC Card Memory Mode) Card Enable -CE1, -CE2 (PC Card I/O Mode) Card Enable -CS0, -CS1 (True IDE Mode) I 7,32 These input signals are used both to select the car d and to indicate to the card whether a byte or a word operation is being performed. -CE2 always accesses the odd byte of the word.-CE1 accesses the even byte or the Odd byte of the word depending on A0 and -CE2. A multiplexing scheme based on A0,-CE1, -CE2 allows 8 bit hosts to access all data on D0-D7. See Table 27, Table 29, Table 31, Table 35, Table 36 and Table 37. This signal is the same as the PC Card Memory Mode signal. In the True IDE Mode, -CS0 is the address range select for the task file registers while -CS1 is used to select the Alternate Status Register and the Device Control Register. While –DMACK is asserted, -CS0 and –CS1 shall be h eld negated and the width of the transfers shall be 16 bits. -CSEL (PC Card Memory Mode) -CSEL (PC Card I/O Mode) -CSEL (True IDE Mode) I 39 This signal is not used for this mode, but should be connected by the host to PC Card A25 or grounded by the host. This signal is not used for this mode, but should be connected by the host to PC Card A25 or grounded by the host. This internally pulled up signal is used to configure this device as a Master or a Slave when configured in the True IDE Mode. When this pin is grounded, this device is configure d as a Master. When the pin is open, this device is configured as a Slave. D15 - D00 (PC Card Memory Mode) D15 - D00 (PC Card I/O Mode) D15 - D00 (True IDE Mode) I/O 31,30,29,28, 27,49,48,47, 6,5,4,3,2, 23, 22, 21 These lines carry the Data, Commands and Status information between the host and the controller. D00 is the LSB of the Even Byte of the Word. D08 is the LSB of the Odd Byte of the Word. This signal is the same as the PC Card Memory Mode signal. In True IDE Mode, all Task File operations occur in byte mode on the low order bus D[7:0] while all data transfers are 16 bit using D[15:0].

Pin Description -INPACK (PC Card Memory Mode) -INPACK (PC Card I/O Mode) Input Acknowledge DMARQ (True IDE Mode) O 43 This signal is not used in this mode. The Input Acknowledge signal is asserted by the CompactFlash Storage Card when the card is selected and responding to an I/O read cycle at the address that is on the address bus. This signal is used by the host to control the enable of any input data buffers between the CompactFlash Sto rage Card and the CPU. This signal is a DMA Request that is used for DMA data transfers between host and device. It shall be asserted by the device when it is ready to transfer data to or from the host. For Multiword DMA transfers, the direction of data transfer is controlled by -IORD and -IOWR. This signal is used in a handshake manner with -DMACK, i.e., the device shall wait until the host asserts -DMACK before negating DMARQ, and reasserting DMARQ if there is more data to transfer. DMARQ shall not be driven when the device is not selected. While a DMA operation is in progress, -CS0 and –CS1 shall be held negated and the width of the transfers shall be 16 bits. If there is no hardware support for DMA mode in the host, this output signal is not used and should not be connected at the host. In this case, the BIOS must report that DMA mode is not supported by the host so that device drivers will not attempt DMA mode. A host that does not support DMA mode and implements both PCMCIA and True-IDE modes of operation need not alter the PCMCIA mode connections while in True-IDE mode as long as this does not prevent proper operation in any mode. -IORD (PC Card Memory Mode) -IORD (PC Card I/O Mode) -IORD (True IDE Mode – Except Ultra DMA Protocol Active) -HDMARDY (True IDE Mode – In Ultra DMA Protocol DMA Read) HSTROBE (True IDE Mode – In Ultra DMA Protocol DMA Write) I 34 This signal is not used in this mode. This is an I/O Read strobe generated by the host. This signal gates I/O data onto the bus from the CompactFlash Storage Card when the card is configured to use the I/O interface. In True IDE Mode, while Ultra DMA mode is not active, this signal has the same function as in PC Card I/O Mode. In True IDE Mode when Ultra DMA mode DMA Read is active, this signal is asserted by the host to indicate that the host is read to receive Ultra DMA data- in bursts. The host may negate -HDMARDY to pause an Ultra DMA transfer. In True IDE Mode when Ultra DMA mode DMA Write is active, this signal is the data out strobe generated by the host. Both the rising and falling edge of HSTROBE cause data to be latched by the device. The host may stop generating HSTROBE edges to pause an Ultra DMA data-out burst.

Pin Description -IOWR (PC Card Memory Mode) -IOWR (PC Card I/O Mode) -IOWR (True IDE Mode – Except Ultra DMA Protocol Active) STOP (True IDE Mode – Ultra DMA Protocol Active) I 35 This signal is not used in this mode. The I/O Write strobe pulse is used to clock I/O dat a on the Card Data bus into the CompactFlash Storage Card controller registers when the CompactFlash Storage Card is configured to use the I/O interface . The clocking shall occur on the negative to positive edge of the signal (trailing edge). In True IDE Mode, while Ultra DMA mode protocol is not active, this signal has the same function as in PC Card I/O Mode. When Ultr a DMA mode protocol is supported, this signal must be negated before enter ing Ultra DMA mode protocol. In True IDE Mode, while Ultra DMA mode protocol is active, the assertion of this signal causes the termination of the Ultra DMA burst. -OE (PC Card Memory Mode) -OE (PC Card I/O Mode) -ATA SEL (True IDE Mode) I 9 This is an Output Enable strobe generated by the host interface. It is used to read data from the CompactFlash Storage Card in Memory Mode and to read the CIS and configuration registers. In PC Card I/O Mode, this signal is used to read the CIS and configuration registers. To enable True IDE Mode this input should be grounded by the host. READY (PC Card Memory Mode) -IREQ (PC Card I/O Mode) INTRQ (True IDE Mode) O 37 In Memory Mode, this signal is set high when the CompactFlash Storage Card is ready to accept a new data transfer operation and is held low when the card is busy. At power up and at Reset, the READY signal is held low (busy) until the CompactFlash Storage Card has completed its power up or reset function. No access of any type should be made to the CompactFlash Storage Card during this time. Note, however, that when a card is powered up and u sed with RESET continuously disconnected or asserted, the Reset fu nction of the RESET pin is disabled. Consequently, the continuous assertion of RESET from the application of power shall not cause the READY signal to remain continuously in the busy state. I/O Operation – After the CompactFlash Storage Card Card has been configured for I/O operation, this signal is used as -Interrupt Request. T his line is strobed low to generate a pulse mode interrupt or held low for a level mode interrupt. In True IDE Mode signal is the active high Interrupt Request to the host.

Pin Description -REG (PC Card Memory Mode) Attribute Memory Select -REG (PC Card I/O Mode) I 44 This signal is used during Memory Cycles to distinguish between Common Memory and Register (Attribute) Memory accesses. High for Common Memory, Low for Attribute Memory. The signal shall also be active (low) during I/O Cycles when the I/O address is on the Bus. -DMACK (True IDE Mode) This is a DMA Acknowledge signal that is asserted by the host in response to DMARQ to initiate DMA transfers. While DMA operations are not active, the card shall ignore the -DMACK signal, including a floating condition. If DMA operation is not supported by a True IDE Mode only host, this signal should be driven high or connected to VCC by the host. A host that does not support DMA mode and implements both PCMCIA and True-IDE modes of operation need not alter the PCMCIA mode connections while in True-IDE mode as long as this does not prevent proper operation all modes. RESET (PC Card Memory Mode) RESET (PC Card I/O Mode) -RESET (True IDE Mode) I 41 The CompactFlash Storage Card is Reset when the RESET pin is high with the following important exception: The host may leave the RESET pin open or keep it continually high from the application of power without causing a continuous Reset of the card. Under either of these conditions, the card shall emerge f rom power-up having completed an initial Reset. The CompactFlash Storage Card is also Reset when the Soft Reset bit in the Card Configuration Option Register is set. This signal is the same as the PC Card Memory Mode signal. In the True IDE Mode, this input pin is the active low hardware reset from the host. VCC (PC Card Memory Mode) VCC (PC Card I/O Mode) VCC (True IDE Mode) -- 13,38 +5 V, +3.3 V power. This signal is the same for all modes. This signal is the same for all modes.

This signal is the same for all modes. This signal is the same for all modes. -WAIT (PC Card Memory Mode) -WAIT (PC Card I/O Mode) IORDY (True IDE Mode – Except Ultra DMA Mode) -DDMARDY (True IDE Mode – Ultra DMA Write Mode) DSTROBE (True IDE Mode – Ultra DMA Read Mode) O 42 The -WAIT signal is driven low by the CompactFla sh Storage Card to signal the host to delay completion of a memory or I/O cycle that is in progress. This signal is the same as the PC Card Memory Mode signal. In True IDE Mode, except in Ultra DMA modes, this output signal may be used as IORDY. In True IDE Mode, when Ultra DMA mode DMA Write is active, this signal is asserted by the host to indicate that the device is read to receive Ultra DMA data-in bursts. The device may negate -DDMARDY to pause an Ultra DMA transfer. In True IDE Mode, when Ultra DMA mode DMA Write is active, this signal is the data out strobe generated by the device. Both the rising and falling edge of DSTROBE cause data to be latched by the host. The device may stop generating DSTROBE edges to pause an Ultra DMA data-out burst. -WE (PC Card Memory Mode) -WE (PC Card I/O Mode) -WE (True IDE Mode) I 36 This is a signal driven by the host and used for strobing memory write data to the registers of the CompactFlash Storage Card when the card is configured in the memory interface mode. It is also used for writing the configuration registers. In PC Card I/O Mode, this signal is used for writing the configuration registers. In True IDE Mode, this input signal is not used and should be connected to VCC by the host.

The host and each card shall be able to drive at least the following load 10 while meeting all AC timing requirements: 100pF with DC current 1.6mA low state and 300 μ A high state. This permits the host to wire two sockets in parallel without derating the card access speeds. 9) Reset Signal: This signal is pulled up to prevent the input from floating when a CFA to PCMCIA adapter is used in a PCMCIA revision 1 host. However, to minimize DC current drain through the pull-up resistor in normal operation the pull-up should be turned off once the Reset signal has been actively driven low by the host. Consequently, the input is specified as an I2Z because the resistor is not necessarily detectable in the input current leakage test. 10) Host and card restrictions for CF Advanced Timing Modes and Ultra DMA modes: Additional Requirements for CF Advanced Timing Modes and Ultra DMA Electrical Requirements for additional required limitations on the implementation of CF Advanced Timing modes and Ultra DMA modes respectively. /square6 Additional Requirements for CF Advanced Timing Mode s The CF Advanced Timing modes include PCMCIA I/O and Memory modes that are 100ns or faster and True IDE PIO Modes 5,6 and Multiword DMA Modes 3,4.

If the sector count is non-zero, it is interpreted as a timer count with each count being 5 milliseconds and the automatic power down mode is enabled. If the sector count is zero, the automatic power down mode is disabled. Note that this time base (5 msec) is different from the ATA specification.
