DMARQ#

 

 

This signal is a DMA request that is used

 

(UDMA

 

 

for DMA data transfers between the host

 

protocol

 

 

and device. This signal is asserted by the

 

active)

 

 

device when it is ready to transfer data to or

 

 

 

 

from the host.

 

 

 

 

For Multiword DMA transfers, the direction

 

 

 

 

of data transfer is controlled by -IORD and

 

 

 

 

-IOWR. This signal is used in a handshake

 

 

 

 

manner with -DMACK (i.e., the device waits

 

 

 

 

until the host asserts (-)DMACK before

 

 

 

 

negating (-)DMARQ, and reasserts

 

 

 

 

(-)DMARQ if there is more data to transfer).

 

 

 

 

In PCMCIA I/O mode, the -DMARQ is

 

 

 

 

ignored by the host while the host is

 

 

 

 

performing an I/O Read cycle to the device.

 

 

 

 

The host does not initiate an I/O Read cycle

 

 

 

 

while -DMARQ is asserted by the device.

 

 

 

 

In True IDE mode, DMARQ is not driven

 

 

 

 

when the device is not selected in the

 

 

 

 

Drive-Head register.

 

 

 

 

While a DMA operation is in progress, -CS0

 

 

 

 

(-CE1) and -CS1 (-CE2) are held negated

 

 

 

 

and the width of the transfers is 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 do not attempt

 

 

 

 

the DMA mode operation.
