The signal must also be active (low) during I/O Cycles when
the I/O address is on the bus.
In True IDE Mode this input signal is used by host in
response to DMARQ to initiate DMA transfers.
The CF Card does not have a write protect switch; therefore,
this signal is held low after the completion of the reset
initialization sequence.
A low signal indicates that a 16 bit or odd byte only operation
can be performed at the addressed port.
Not defined in IDE Mode.
This signal is not used in this mode.
The Input Acknowledge signal is asserted by the CF Card
when it is selected and responding to an I/O read cycle at the
address that is on the bus. The host uses this signal to
control the enable of any input data buffers between the CF
Card and the host’s CPU.
In True IDE Mode this signal is asserted by the CF Card
when it is ready to transfer data to/from the host. Data
direction is controlled by -IORD and -IOWR. This signal is
used in a handshake manner with -DMACK.
This signal is asserted high as since a battery is not used
with this product.
This signal is asserted low to alert the host to changes in the
RDY/-BSY and Write Protect states. Its use is controlled by
the Configuration and Status Register.
In True IDE Mode, this input/output signal is the Pass
Diagnostic signal in the Master/Slave handshake protocol.
This signal is not used by the CF Card, and is pulled up to
VCC through a 4.7K ohm resistor.
This signal is not used by the CF Card, and is pulled up to
VCC through a 4.7K ohm resistor.
This signal is not used by the CF Card, and is pulled up to

When RESET is high, this signal resets the CF Card. The CF Card
is reset only at power up if this signal is left high or open from
power-up. The CF Card can also be reset when the soft reset bit in
the Configuration Option Register is set.
