MC68EC020—The processor negates AS and DS during state S5. It holds the address
address valid during S5 to provide address hold time for memory systems. R/W, SIZ1–
SIZ0, and FC2–FC0 also remain valid throughout S5.
The external device keeps its data and DSACK1/DSACK0 signals asserted until it
detects the negation of AS or DS (whichever it detects first). The device must remove
its data and negate DSACK1/DSACK0 within approximately one clock period after
sensing the negation of AS or DS. DSACK1/DSACK0 signals that remain asserted
beyond this limit may be prematurely detected for the next bus cycle.
