Description

-INPACK

O

43

This signal is not used in this mode.

(PC Card Memory Mode except

 

 

 

 

Ultra DMA Protocol Active)

 

 

 

 

 

 

 

 

The Input Acknowledge signal is asserted by the CompactFlash Storage Card

-INPACK

 

 

when the card is selected and responding to an I/O read cycle at the address

(PC Card I/O Mode except Ultra

 

 

that is on the address bus. This signal is used by the host to control the enable of

DMA Protocol Active)

 

 

any input data buffers between the CompactFlash Storage Card and the CPU.

Input Acknowledge

 

 

 

 

 

 

 

 

 

 

Hosts that support a single socket per interface logic, such as for Advanced

 

 

 

 

Timing Modes and Ultra DMA operation may ignore the –INPACK signal from

 

 

 

 

the device and manage their input buffers based solely on Card Enable signals.

-DMARQ

 

 

This signal is a DMA Request that is used for DMA data transfers between host

(PC Card Memory Mode -Ultra

 

 

and device. It shall be asserted by the device when it is ready to transfer data to

DMA Protocol Active)

 

 

or from the host. For Multiword DMA transfers, the direction of data transfer is

-DMARQ

 

 

controlled by -HIOE and -IOWR. This signal is used in a handshake manner with

 

 

(-)DMACK, i.e., the device shall wait until the host asserts (-)DMACK before

(PC Card I/O Mode -Ultra DMA

 

 

 

 

negating (-)DMARQ, and re-asserting (-)DMARQ if there is more data to

Protocol Active)

 

 

 

 

transfer.

DMARQ

 

 

 

 

 

 

(True IDE Mode)

 

 

In PCMCIA I/O Mode, the -DMARQ shall be ignored by the host while the host is

 

 

 

 

performing an I/O Read cycle to the device. The host shall not initiate an I/O

 

 

 

 

Read cycle while -DMARQ is asserted by the device.

 

 

 

 

In True IDE Mode, DMARQ shall not be driven when the device is not selected in

 

 

 

 

the Drive-Head register.

 

 

 

 

While a DMA operation is in progress, -CS0 (-CE1)and -CS1 (-CE2) shall be

 

 

 

 

held negated and the width of the transfers shall be 16 bits.

 

 

 

 

If there is no hardware support for True IDE DMA mode in the host, this output

 

 

 

 

signal is not used and should not be connected at the host. In this case, the

 

 

 

 

BIOS must report that DMA mode is not supported by the host so that device

 

 

 

 

drivers will not attempt DMA mode operation.

 

 

 

 

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 in any mode.

-HIOE

I

34

This signal is not used in this mode.

(PC Card Memory Mode except

 

 

 

 

Ultra DMA Protocol Active)

 

 

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

 

 

 

 

-HIOE

 

 

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

(PC Card I/O Mode except Ultra

 

 

the I/O interface.

DMA Protocol Active)

 

 

 

 

-HIOE

 

 

In True IDE Mode, while Ultra DMA mode is not active, this signal has the same

 

 

function as in PC Card I/O Mode.

(True IDE Mode – Except Ultra

 

 

 

 

 

 

DMA Protocol Active)

 

 

 

 

 

 

 

 

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

-HDMARDY

 

 

by the host to indicate that the host is ready to receive Ultra DMA data-in bursts.

(All Modes - Ultra DMA Protocol

 

 

The host may negate – HDMARDY to pause an Ultra DMA transfer.

DMA Read)

 

 

 

 

HSTROBE

 

 

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

 

 

out strobe generated by the host. Both the rising and falling edge of HSTROBE

(All Modes - Ultra DMA Protocol

 

 

DMA Write)

 

 

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

 

 

 

 

HSTROBE edges to pause an Ultra DMA data-out burst.
