Description

-VS1

O

33

Voltage Sense Signals. -VS1 is grounded on the Card and sensed by the Host

-VS2

so that the CompactFlash Storage Card CIS can be read at 3.3 volts and -VS2 is

 

40

(PC Card Memory Mode)

 

reserved by PCMCIA for a secondary voltage and is not connected on the Card.

 

 

-VS1

 

 

This signal is the same for all modes.

-VS2

 

 

 

 

(PC Card I/O Mode)

 

 

 

 

-VS1

 

 

This signal is the same for all modes.

-VS2

 

 

 

 

(True IDE Mode)

 

 

 

 

-WAIT

O

42

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

(PC Card Memory Mode – Except

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

 

 

Ultra DMA Protocol Active)

 

 

 

 

-WAIT

 

 

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

(PC Card I/O Mode –Except Ultra

 

 

 

 

DMA Protocol Active)

 

 

 

 

IORDY

 

 

In True IDE Mode, except in Ultra DMA modes, this output signal may be used

 

 

as IORDY.

(True IDE Mode – Except Ultra

 

 

DMA Protocol Active)

 

 

 

 

-DDMARDY

 

 

In all modes, when Ultra DMA mode DMA Write is active, this signal is asserted

 

 

by the device during a data burst to indicate that the device is ready to receive

(All Modes – Ultra DMA Write

 

 

 

 

Ultra DMA data out bursts. The device may negate -DDMARDY to pause an

Protocol Active)

 

 

 

 

Ultra DMA transfer.

 

 

 

 

DSTROBE

 

 

In all modes, when Ultra DMA mode DMA Read is active, this signal is the data in

 

 

strobe generated by the device. Both the rising and falling edge of DSTROBE

(All Modes – Ultra DMA Read

 

 

Protocol Active)

 

 

cause data to be latched by the host. The device may stop generating

 

 

 

 

DSTROBE edges to pause an Ultra DMA data in burst.

-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

(True IDE Mode)

 

 

by the host.

24

Memory Mode – The CompactFlash Storage Card does not have a write protect

(PC Card Memory Mode)

switch. This signal is held low after the completion of the reset initialization

sequence.

-IOIS16

 

 

I/O Operation – When the CompactFlash Storage Card is configured for I/O

(PC Card I/O Mode)

 

 

Operation Pin 24 is used for the -I/O Selected is 16 Bit Port (-IOIS16) function. A

 

 

 

 

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

 

 

 

 

(True IDE Mode)

 

 

a word data transfer cycle.
