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 Storage Card and the CPU.
Hosts that support a single socket per interface logic, such as for Advanced
Timing Modes and Ultra DMA operation may ignore the –INPACK signal from
the device and manage their input buffers based solely on Card Enable signals.
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 -HIOE 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 re-asserting (-)DMARQ if there is more data to
transfer.
In PCMCIA I/O Mode, the
performing an I/O Read cycle to the device. The host shall not initiate an I/O
Read cycle while
In True IDE Mode, DMARQ shall not be driven when the device is not selected in
the Drive-Head register.
While a DMA operation is in progress, -CS0 (-CE1)and -CS1 (-CE2) shall be
held negated and the width of the transfers shall be 16 bits.
If there is no hardware support for True IDE 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 operation.
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 in any mode.
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 all modes when Ultra DMA mode DMA Read is active, this signal is asserted
by the host to indicate that the host is ready to receive Ultra DMA data-in bursts.
The host may negate – HDMARDY to pause an Ultra DMA transfer.
In all modes 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.
