-IORD

 

I

34

This signal is not used in this mode.

(PC Card Memory Mode)

 

 

 

 

 

-IORD

 

 

 

This is an I/O Read strobe generated by the host. This signal gates I/O data onto

 

 

 

the bus from the CompactFlash Storage Card when the card is configured to use

(PC Card I/O Mode)

 

 

 

 

 

 

the I/O interface.

 

 

 

 

 

-IORD

 

 

 

In True IDE Mode, this signal has the same function as in PC Card I/O Mode.

 

 

 

 

 

(True IDE Mode )

 

 

 

 

 

 

 

 

 

 

-IOWR

 

I

35

This signal is not used in this mode.

(PC Card Memory Mode)

 

 

 

 

 

 

 

 

-IOWR

 

 

 

The I/O Write strobe pulse is used to clock I/O data on the Card Data bus into

(PC Card I/O Mode)

 

 

 

the CompactFlash Storage Card controller registers when the CompactFlash

 

 

 

 

 

Storage Card is configured to use the I/O interface.

 

 

 

 

 

The clocking shall occur on the negative to positive edge of the signal (trailing

 

 

 

 

 

edge).

-IOWR

 

 

 

In True IDE Mode, this signal has the same function as in PC Card I/O Mode.

Description

 

 

 

 

 

-OE

 

I

9

This is an Output Enable strobe generated by the host interface. It is used to

(PC Card Memory Mode)

 

 

 

read data from the CompactFlash Storage Card in Memory Mode and to read

 

 

 

 

 

the CIS and configuration registers.

-OE

 

 

 

In PC Card I/O Mode, this signal is used to read the CIS and configuration

(PC Card I/O Mode)

 

 

 

registers.

-ATA SEL

 

 

 

To enable True IDE Mode this input should be grounded by the host.

(True IDE Mode)

 

 

 

 

 

READY

 

O

37

In Memory Mode, this signal is set high when the CompactFlash Storage Card

(PC Card Memory Mode)

 

 

 

is ready to accept a new data transfer operation and is held low when the card is

 

 

 

 

 

busy.

 

 

 

 

 

At power up and at Reset, the READY signal is held low (busy) until the

 

 

 

 

 

CompactFlash Storage Card has completed its power up or reset function. No

 

 

 

 

 

access of any type should be made to the CompactFlash Storage Card during

 

 

 

 

 

this time.

 

 

 

 

 

Note, however, that when a card is powered up and used with RESET

 

 

 

 

 

continuously disconnected or asserted, the Reset function of the RESET pin is

 

 

 

 

 

disabled. Consequently, the continuous assertion of RESET from the

 

 

 

 

 

application of power shall not cause the READY signal to remain continuously in

 

 

 

 

 

the busy state.

-IREQ

 

 

 

I/O Operation – After the CompactFlash Storage Card Card has been

(PC Card I/O Mode)

 

 

 

configured for I/O operation, this signal is used as -Interrupt Request. This line is

 

 

 

 

 

strobed low to generate a pulse mode interrupt or held low for a level mode

 

 

 

 

 

interrupt.

INTRQ

 

 

 

In True IDE Mode signal is the active high Interrupt Request to the host.
