Notes:
1.
WAIT is driven per OE# assertion during synchronous array or non-array read, and can be configured to
assert either during or one data cycle before valid data.
This diagram illustrates the case in which an n-word burst is initiated to the flash memory array and it is
terminated by CE# deassertion after the first word in the burst.

Notes:
1.
WAIT is driven per OE# assertion during synchronous array or non-array read. WAIT asserted during
initial latency and deasserted during valid data (RCR[10] = 0 Wait asserted low).
At the end of Word Line; the delay incurred when a burst access crosses a 16-word boundary and the
starting address is not 4-word boundary aligned.
