Pin Description -REG (PC Card Memory Mode– Except Ultra DMA Protocol Active) Attribute Memory Select -REG (PC Card I/O Mode –Except Ultra DMA Protocol Active) 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. In PC Card Memory Mode, when Ultra DMA Protocol is supported by the host and the host has enabled Ultra DMA protocol on the card the, host shall keep the -REG signal negated during the execution of any DMA Command by the device. The signal shall also be active (low) during I/O Cycles when the I/O address is on the Bus. In PC Card I/O Mode, when Ultra DMA Protocol is supported by the host and the host has enabled Ultra DMA protocol on the card the, host shall keep the -REG signal asserted during the execution of any DMA Command by the device. -DMACK (PC Card Memory Mode when Ultra DMA Protocol Active) DMACK (PC Card I/O Mode when Ultra DMA Protocol Active) -DMACK (True IDE Mode) I 44 This is a DMA Acknowledge signal that is asserted by the host in response to (-)DMARQ to initiate DMA transfers. In True IDE Mode, 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 PC Card and True-IDE modes of operation need not alter the PC Card 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 from 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. |
