nWAIT PIN OPERATION
If the WAIT corresponding to each memory bank is enabled, the nOE duration should be prolonged by the external
nWAIT pin while the memory bank is active. nWAIT is checked from tacc-1. nOE will be deasserted at the next
clock after sampling nWAIT is high. The nWE signal have the same relation with nOE.
