NOTES:.
1. All timing is the same for left and right ports. Port “A” may be either left or right port. Port “B” is the opposite from port “A”.
2. See Interrupt Truth Table II.
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.
