Description

This signal is not asserted for all modes.

This signal is not asserted for all modes.

This signal is not asserted for all modes.

This is a signal driven by the host and used for strobing

memory write data to the registers of the Compact Flash Card

when the card is configured in the memory interface mode. It

is also used for writing the configuration registers.

In PC Card I/O Mode, this signal is used for writing the

configuration registers.

In True IDE Mode this input signal is not used and should be

connected to VCC by the host.

Memory Mode – The Compact Flash Card does not have a

write protect switch. This signal is held low after the

completion of the reset initialization sequence.

I/O Operation – When the Compact Flash Card is configured

for I/O Operation, Pin 24 is used for the –I/O Selected is 16

Bit Port (-IOIS16) function. A Low signal indicates that a 16

bit or odd byte only operation can be performed at the

addressed port.

In True IDE Mode this output signal is asserted low when

this device is expecting a word data transfer cycle.
