Bits 2n + 1, 2n—Area n (6–2, 0) Intercycle Idle Specification (AnIW1, AnIW0): Specify the
number of idles inserted between bus cycles when switching between physical space area n (6–2,
0) and another space or between a read access and a write access in the same physical space.
11.2.4
Wait state control register 2 (WCR2) is a 16-bit readable/writable register that specifies the
number of wait state cycles inserted for each area. It also specifies the data access pitch for burst
memory accesses. This allows direct connection of even low-speed memories without an external
circuit. WCR2 is initialized to H'FFFF by a power-on reset. It is not initialized by a manual reset
or in standby mode.
