Burst Sequence
The Burst Sequence (BS) bit selects linear-burst sequence (default). Only linear-burst
sequence is supported.
lengths, as well as the effect of the Burst Wrap (BW) setting.
Clock Edge
The Clock Edge (CE) bit selects either a rising (default) or falling clock edge for CLK.
This clock edge is used at the start of a burst cycle, to output synchronous data, and to
assert/deassert WAIT.
