Motorola Read Cycle Timing
Note 1: Function of DTACK is described logically as:
DTACK = CS × DACKA × DACKB × INTAi + DS × R/W ) i.e. in accordance with
common specifications of Motorola read accesses the timing of DTACK is
normally determined by DS.
Note 2: DRR is reset with the falling edge of DS during the last read access to RFIFO.
