NOTES:
1. V
DD
, OPT
X
, and V
DDQX
must be set to appropriate operating levels prior to
applying inputs on the I/Os and controls for that port.
2. OPT
X
selects the operating voltage levels for the I/Os and controls on that port.
If OPT
X
is set to VIH (3.3V), then that port's I/Os and controls will operate at 3.3V
levels and V
DDQX
must be supplied at 3.3V. If OPT
X
is set to VIL (0V), then that
port's I/Os and address controls will operate at 2.5V levels and V
DDQX
must be
supplied at 2.5V. The OPT pins are independent of one another—both ports can
operate at 3.3V levels, both can operate at 2.5V levels, or either can operate
at 3.3V with the other at 2.5V.
3. When
REPEAT
X
is asserted, the counter will reset to the last valid address loaded
via
ADS
X
.
4. Accesses by the ports into specific banks are controlled by the bank address
pins under the user's direct control: each port can access any bank of memory
with the shared array that is not currently being accessed by the opposite port
(i.e., BA
0L
- BA
5L
≠
BA
0R
- BA
5R
). In the event that both ports try to access the
same bank at the same time, neither access will be valid, and data at the two
specific addresses targeted by the ports within that bank may be corrupted (in
the case that either or both ports are writing) or may result in invalid output (in
the case that both ports are trying to read).
