DISK DRIVE OPERATION

6.7.4.4Host pausing an Ultra DMA data in burst

The values for the timings for each of the Ultra DMA modes are contained in 6.7.4.2.

DMARQ (device)

DMACK-

(host)

STOP (host)

tSR

HDMARDY-

(host)

DSTROBE

(device)

DD(15:0)

(device)

tRP

tRFS

NOTES −

1 The host may assert STOP to request termination of the Ultra DMA burst no sooner than tRP after HDMARDY- is negated.

2 If the tSR timing is not satisfied, the host may receive zero, one, or two more data words from the device.
