The DREQ/DACK(F) signals are the high priorty DMA signals and are shared between all option slots.
|
||||
The DREQ/DACK(S) signals are the lower priority DMA signals and are local to each slot, with the
|
||||
exception of slot 5 which does not provide low priority DMA signals. The RDY/EOP(S) signals are
|
||||
also connected to all 5 options slots since the DREQ(S) signals are all connected to the same

DMA controller.
