Waveform of Interrupt Timing(1)
Truth Table III — Interrupt Flag(1)
NOTES:
1. All timing is the same for left and right ports. Port “A” may be either the left or right port. Port “B” is the port opposite from “A”.
2. See Interrupt truth table.
3. Timing depends on which enable signal (
CE or R/W) is asserted last.
4. Timing depends on which enable signal (
CE or R/W) is de-asserted first.
NOTES:
1. Assumes
BUSYL = BUSYR = VIH.
2. If
BUSYL = VIL, then no change.
3. If
BUSYR = VIL, then no change.
