This is a bus access request cycle initiated by the internal bus master and with the external bus
as the target. CSn is always high during this cycle. In the next cycle A27 to A0 and the write
data change.
For the first page access, the wait operation from internal bus access start to the wait end cycle
is the same as in normal access.
This is the final cycle in the first series of read cycle wait or write cycle wait cycles. In write
access, the second and subsequent page accesses start from the next cycle, unless a write data
output delay cycle has been specified (with a value other than 0). The RD or WR signal is
negated (high level) in the next cycle if the RD assert wait or WD assert wait setting is other
than 0. If the RD assert wait or WD assert wait setting is 0, the RD or WR signal continues to
be asserted (low level). The CSn signal is not negated and continues to be asserted (low level).
In page read access, the succeeding bus access starts without waiting for the read data sample
cycle (Trd).
