WAIT Polarity (RCR.10)
The WAIT Polarity bit (WP), RCR.10 determines the asserted level (V
When WP is set, WAIT is asserted high. When WP is cleared, WAIT is asserted low
(default). WAIT changes state on valid clock edges during active bus cycles (CE#
asserted, OE# asserted, RST# deasserted).
WAIT Delay (RCR.8)
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 (RCR.7)
The Burst Sequence (BS) bit selects linear-burst sequence (default). Only linear-burst
sequence is supported.
