(4)
RDNCR can be used to select either of two negation timings (at the end of the read cycle or one
half-state before the end of the read cycle) for the read strobe (RD) used in the basic bus interface
space.
(5)
Some external I/O devices require a setup time and hold time between address and CS signals and
strobe signals such as RD, HWR, and LWR. CSACR can be used to insert states in which only the
CS, AS, and address signals are asserted before and after a basic bus space access cycle.
