Note:
15.The internal Write time of the memory is defined by the overlap of WE, CE
= V
or CE
=
V
, BHE and/or BLE = V
. All signals must be ACTIVE to initiate a
write and any of these signals can terminate a write by going INACTIVE. The data input set-up and hold timing should be referenced to the edge of the signal
that terminates the write.
