REGISTER SUMMARY
MOTOROLA

RES — Queue 2 Resume
0 = After suspension, begin execution with the first CCW in queue 2 or the current
subqueue.
1 = After suspension, begin execution with the aborted CCW in queue 2.
BQ2[5:0] — Beginning of Queue 2
The BQ2 field indicates the CCW location where queue 2 begins. To allow the length
of queue 1 and queue 2 to vary, a programmable pointer identifies the CCW table lo-
cation where queue 2 begins. The BQ2 field also serves as an end-of-queue condition
for queue 1.
