Truth Table III — Interrupt Flag(1)
Waveform of Interrupt Timing(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 port “A”.
2. See Interrupt Truth Table III.
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.
