When the pin is high, this signal Resets the CompactFlasgh
Storage Card. The CompactFlash Storage Card is Reset only at
power up if this pin is left high or open from power-up .The
CompactFlash Storage Card is also Reset when the Soft Reset bit
in the Card Configuration Option Register is set.
In the True IDE Mode this input pin is the active low hardware reset
from the host.

CompactFlash Storage Card CIS can be read at 3.3 volts and
−
The −WAIT signal is driven low by the CompactFlash Storage Card
to indicate the host to delay completion of a memory or I/O cycle
that is in progress.
This CompactFlash Storage Card outputs always high.
This CompactFlash Storage Card outputs always high.
This is a signal driven by the host and used for strobing memory
write data to the registers of the CompactFlash Storage Card when
the card is configured I the memory interface mode. It is also used
for writing the configuration registers.
In PC Card I/O Mode, this signal is used only for writing the
Attribute memory.
In True IDE Mode this input signal is not used and should be
connected to VCC by the host.
Memory Mode-The CompactFlash Storage Card does not have a
write protect switch. This signal is held low after the completion of
the reset initialization sequence.
This signal is asserted when 16 bit or odd byte access to task file
registers is accepted.
In True IDE Mode this output signal is asserted low when this
device is expecting a word data transfer cycle.
VS2 is reserved by PCMCIA for a secondary voltage.
