The -WAIT signal is driven low by the CompactFlash Storage Card to signal the

(PC Card Memory Mode)

 

 

 

host to delay completion of a memory or I/O cycle that is in progress.

 

 

 

 

 

-WAIT

 

 

 

This signal is the same as the PC Card Memory Mode signal.

Description

 

 

 

 

 

-WE

 

I

36

This is a signal driven by the host and used for strobing memory write data to the

(PC Card Memory Mode)

 

 

 

registers of the CompactFlash Storage Card when the card is configured in the

 

 

 

 

 

memory interface mode. It is also used for writing the configuration registers.

-WE

 

 

 

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

(PC Card I/O Mode)

 

 

 

 

 

-WE

 

 

 

In True IDE Mode, this input signal is not used and should be connected to VCC

Low signal indicates that a 16 bit or odd byte only operation can be performed at

 

 

 

 

 

the addressed port.

-IOCS16

 

 

 

In True IDE Mode this output signal is asserted low when this device is expecting
