Description
-INPACK
(PC Card Memory Mode)
O
43
This signal is not used in this mode.
-INPACK
(PC Card I/O Mode)
Input Acknowledge
The Input Acknowledge signal is asserted by the
CompactFlash
TM
Storage Card or CF+ 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 CompactFlash
TM
Storage Card or CF+
Card and the CPU.
-DMARQ
(True IDE Mode)
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, ie: the
device shall wait until the host asserts –DMACK before
negating DMARQ, and re-asserting 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.
BVD1
(PC Card Memory Mode)
I/O
46
This signal is asserted high as the BVD1 signal since a
battery is not used with this product.
-STSCHG
(PC Card I/O Mode)
Status Changed
This signal is asserted low to alert the host to changes in
the RDY/-BSY and Write Protect states, while the I/O
interface is configured. Its use is controlled by the Card
Config and Status Register.
-PDIAG
(True IDE Mode)
In the True IDE Mode, this input / output is the Pass
Diagnostic signal in the Master / Slave handshake
protocol.
