NOTES:
1. All timng is the same for left and right ports. Port
“
A
”
may be either the left or right port. Port
“
B
”
is the port opposite fromport
“
A
”
.
2. See Interrupt Truth Table.
3. Timng depends on which enable signal (
CE
or R/
W
) is asserted last.
4. Timng depends on which enable signal (
CE
or R/
W
) is de-asserted first.
5. Refer to Chip Enable Truth Table.
NOTES:
1. Assumes

2. If
BUSY
L
= V

, then no change.
4.
INT
L
and
