Description

-REG

I

44

This signal is used during Memory Cycles to distinguish between Common

Memory and Register (Attribute) Memory accesses. High for Common Memory,

(PC Card Memory Mode– Except

 

 

 

 

Low for Attribute Memory.

Ultra DMA Protocol Active)

 

 

 

 

 

 

Attribute Memory Select

 

 

In PC Card Memory Mode, when Ultra DMA Protocol is supported by the host

 

 

 

 

and the host has enabled Ultra DMA protocol on the card the, host shall keep the

 

 

 

 

-REG signal negated during the execution of any DMA Command by the device.

-REG

 

 

The signal shall also be active (low) during I/O Cycles when the I/O address is on

(PC Card I/O Mode –Except Ultra

 

 

the Bus.

DMA Protocol Active)

 

 

In PC Card I/O Mode, when Ultra DMA Protocol is supported by the host and the

 

 

 

 

 

 

 

 

host has enabled Ultra DMA protocol on the card the, host shall keep the -REG

 

 

 

 

signal asserted during the execution of any DMA Command by the device.

-DMACK

 

 

This is a DMA Acknowledge signal that is asserted by the host in response to

(PC Card Memory Mode when

 

 

(-)DMARQ to initiate DMA transfers.

Ultra DMA Protocol Active)

 

 

In True IDE Mode, while DMA operations are not active, the card shall ignore the

DMACK

 

 

 

 

(-)DMACK signal, including a floating condition.

(PC Card I/O Mode when Ultra

 

 

 

 

 

 

DMA Protocol Active)

 

 

If DMA operation is not supported by a True IDE Mode only host, this signal

-DMACK

 

 

should be driven high or connected to VCC by the host.

 

 

 

 

(True IDE Mode)

 

 

A host that does not support DMA mode and implements both PC Card and

 

 

 

 

True-IDE modes of operation need not alter the PC Card mode connections

 

 

 

 

while in True-IDE mode as long as this does not prevent proper operation all

 

 

 

 

modes.

RESET

I

41

The CompactFlash Storage Card is Reset when the RESET pin is high with the

(PC Card Memory Mode)

 

 

following important exception:

 

 

 

 

The host may leave the RESET pin open or keep it continually high from the

 

 

 

 

application of power without causing a continuous Reset of the card. Under

 

 

 

 

either of these conditions, the card shall emerge from power-up having

 

 

 

 

completed an initial Reset.

 

 

 

 

The CompactFlash Storage Card is also Reset when the Soft Reset bit in the

 

 

 

 

Card Configuration Option Register is set.

RESET

 

 

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

(PC Card I/O Mode)

 

 

 

 

-RESET

 

 

In the True IDE Mode, this input pin is the active low hardware reset from the

(True IDE Mode)

 

 

host.

 

 

 

 

 

 

 

 

VCC

--

13,38

+5 V, +3.3 V power.

(PC Card Memory Mode)

 

 

 

 

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)
