WAIT Delay
The WAIT Delay (WD) bit controls the WAIT assertion-delay behavior during
synchronous burst reads. WAIT can be asserted either during or one data cycle before
valid data is output on DQ[15:0]. When WD is set, WAIT is deasserted one data cycle
before valid data (default). When WD is cleared, WAIT is deasserted during valid data.
Burst Sequence
The Burst Sequence (BS) bit selects linear-burst sequence (default). Only linear-burst
sequence is supported.
