TS1G~32GCF133				133X CompactFlash Card
	Signal Name	Dir.	Pin	Description
-INPACK		O	43	This signal is not used in this mode.
(PC Card Memory Mode)
-INPACK				The Input Acknowledge signal is asserted by the CompactFlash Storage Card
(PC Card I/O Mode)				when the card is selected and responding to an I/O read cycle at the address that
Input Acknowledge				is on the address bus. This signal is used by the host to control the enable of any
				input data buffers between the CompactFlash Storage Card and the CPU.
DMARQ				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
(True IDE Mode)
				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		I	34	This signal is not used in this mode.
(PC Card Memory Mode)
-IORD				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
(PC Card I/O Mode)
				the I/O interface.
-IORD				In True IDE Mode, while Ultra DMA mode is not active, this signal has the same
				function as in PC Card I/O Mode.
(True IDE Mode – Except
Ultra DMA Protocol Active)
-HDMARDY				In True IDE Mode when Ultra DMA mode DMA Read is active, this signal is
(True IDE Mode – In Ultra				asserted by the host to indicate that the host is read to receive Ultra DMA data-in
DMA Protocol DMA Read)				bursts. The host may negate -HDMARDY to pause an Ultra DMA transfer.
HSTROBE				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
(True IDE Mode – In Ultra
				HSTROBE cause data to be latched by the device. The host may stop
DMA Protocol DMA Write)
				generating HSTROBE edges to pause an Ultra DMA data-out burst.
