Description

 

 

 

 

 

 

 

 

VCC

 

 

This signal is the same for all modes.

 

 

(PC Card I/O

 

 

 

 

 

mode)

 

 

 

 

 

 

 

 

 

 

 

VCC

 

 

This signal is the same for all modes.

 

 

(True IDE mode)

 

 

 

 

 

 

 

 

 

 

 

-VS1, -VS2

33, 40

O

Voltage Sense Signals.

 

 

 

 

 

-VS1 is grounded so that the

 

 

 

 

 

SiliconDrive CF CIS can be read at

 

 

 

 

 

3.3V.

 

 

 

 

 

-VS2 is reserved by PC Card for a

 

 

 

 

 

secondary voltage.

 

 

-VS1, -VS2

 

 

This signal is the same for all modes.

 

 

(PC Card I/O

 

 

 

 

 

mode)

 

 

 

 

 

 

 

 

 

 

 

-VS1, -VS2

 

 

This signal is the same for all modes.

 

 

(True IDE mode)

 

 

 

 

 

 

 

 

 

 

 

-WAIT

42

O

The -WAIT signal is driven low by the

 

 

(PC Card memory

 

 

SiliconDrive CF to signal the host to

 

 

mode)

 

 

delay completion of a memory or I/O

 

 

 

 

 

cycle that is in progress.

 

 

-WAIT

 

 

This signal is the same as the PC

 

 

(PC Card I/O

 

 

Card Memory Mode signal.

 

 

mode)

 

 

 

 

 

 

 

 

 

 

 

-IORDY

 

 

In true IDE mode, this output signal

 

 

(True IDE mode)

 

 

may be used as IORDY.

 

 

 

 

 

 

 

 

-WE

36

I

This is a signal driven by the host and

 

 

(PC Card memory

 

 

used for strobing memory write data

 

 

mode)

 

 

to the registers of the SiliconDrive CF

 

 

 

 

 

when the card is configured in the

 

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

-WE

(PC Card I/O mode)

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