This signal is not used in this mode.

 

 

(PC Card memory

 

 

 

 

mode)

 

 

 

 

-IORD

(PC Card I/O mode)

This is an I/O read strobe generated by the host. This signal gates I/O data onto the bus from the SiliconDrive CF when the card is configured to use the I/O interface.

-IORD

 

 

In true IDE mode, this signal has the

(True IDE mode)

 

 

same function as the PC Card I/O

 

 

 

mode.

-IOWR

35

I

This signal is not used in this mode.

(PC Card memory

 

 

 

mode)

 

 

 

 

 

 

 

-IOWR

 

 

The I/O write strobe pulse is used to

(PC Card I/O

 

 

clock I/O data on the Card data bus

mode)

 

 

into the SiliconDrive CF controller

 

 

 

registers when the SiliconDrive CF is

 

 

 

configured to use the I/O interface.

 

 

 

The clocking occurs on the negative-

 

 

 

to-positive edge of the signal (the

 

 

 

trailing edge).

 

 

 

 

-IOWR

 

 

In true IDE mode, this signal has the

(True IDE mode)

 

 

same function as the PC Card I/O

 

 

 

mode.

-OE

9

I

This is an output enable strobe

(PC Card memory

 

 

generated by the host interface, which

mode)

 

 

is used to read:

 

 

 

• Data from the SiliconDrive CF in

 

 

 

memory mode.

 

 

 

• The CIS and configuration

 

 

 

registers.

 

 

 

 

-OE

 

 

In PC Card I/O mode, this signal is

(PC Card I/O

 

 

used to read the CIS and

mode)

 

 

configuration registers.
