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 ) is asserted last.
4. Timing depends on which enable signal ( CE or R/ W ) is de-asserted first.
5. Refer to Chip Enable Truth Table.

NOTES:
1. Assumes BUSY L = BUSY R =V IH .
2. If BUSY L = V IL , then no change.
3. If BUSY R = V IL , then no change.
4. INT L and INT R must be initialized at power-up.
5. Refer to Chip Enable Truth Table.
