10.2.3
Wait state control register 1 (WCR1) is a 16-bit readable/writable register that specifies the
number of idle (wait) state cycles inserted for each area. For some memories, data bus drive may
not be turned off quickly even when the read signal from the external device is turned off. This
can result in conflicts between data buses when consecutive memory accesses are to different
memories or when a write immediately follows a memory read. This LSI automatically inserts the
number of idle states set in WCR1 in those cases.
WCR1 is initialized to H'3FF3 by a power-on reset. It is not initialized by a manual reset or in
standby mode, and retains its contents.
