Timing Diagrams
FAST MEMORY MODE (8 BIT DATA BUS)
CONDITIONS: SMODE = DG. Bus = DG
NOTE: With SMODE = DG, the internal logic diables the output latches from being updated during a read. The EOC output is LOW continuously.
DMA MODE (16 BIT DATA BUS)
CONDITIONS: SMODE = V+, CS = WR = RD = DG, Bus = V+, HBE = DG or V+
NOTE: EOC output is low continuously
