Device Terminating an Ultra DMA Data-In Burst
diagram is shown in below: Ultra DMA Data-In Burst Device Termination Timing. The timing parameters
are specified in Page 12: Ultra DMA Data Burst Timing Requirements and are described in Page 13:
Ultra DMA Data Burst Timing Descriptions.
The following steps shall occur in the order they are listed unless otherwise specifically allowed:
(a) The device shall not pause an Ultra DMA data burst until at least one data word of an Ultra DMA data
(b) The device shall pause an Ultra DMA data burst by not generating DSTROBE edges.
(c) NOTE − The host shall not immediately assert STOP to initiate Ultra DMA data burst termination
(d) The device shall resume an Ultra DMA data burst by generating a DSTROBE edge.
Notes: The definitions for the STOP, HDMARDY, and DSTROBE signal lines are no longer in effect after DMARQ

burst has been transferred.
when the device stops generating STROBE edges. If the device does not negate DMARQ, in order to
initiate Ultra DMA data burst termination, the host shall negate -HDMARDY and wait t
