1. Assumes
BUSYL = BUSYR = VIH.
2. If
BUSYL = VIL, then no change.
3. If
BUSYR = VIL, then no change.
4.
INTR and INTL must be initialized at power-up.
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.
3. Timing depends on which enable signal (
CE or R/W) asserted last.
4. Timing depends on which enable signal (
CE or R/W) is de-asserted first.
