Truth Table II – Non-Contention Read/Write Control
NOTES:
1. Chip Enable references are shown above with the actual CE0 and CE1 levels, CE is a reference only.
2. Port "A" and "B" references are located where CE is used.
3. "H" = V
IH and "L" = VIL
Truth Table I – Chip Enable
(1,2,3)
Truth Table III – Semaphore Read/Write Control
NOTES:
1. A
0L — A14L ≠ A0R — A14R.
2. Refer to Chip Enable Truth Table.
NOTES:
1. There are eight semaphore flags written to I/O
0 and read from all the I/Os (I/O0-I/O15). These eight semaphore flags are addressed by A0-A2.
2. Refer to Chip Enable Truth Table.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS
may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those
indicated in the operational sections of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect
reliability.

NOTES:
1. 'X' in part numbers indicates power rating (S or L).
2. V
DD = 3.3V, TA = +25°C, and are not production tested. IDD DC = 90mA (Typ.)
3. At f = f
MAX, address and control lines (except Output Enable) are cycling at the maximum frequency read cycle of 1/tRC, and using “AC Test Conditions” of input
levels of GND to 3V.
4. f = 0 means no address or control lines change.
5. Port "A" may be either left or right port. Port "B" is the opposite from port "A".
