6.2.4
BCRH is an 8-bit readable/writable register that selects enabling or disabling of idle cycle
insertion, and the memory interface for area 0.
BCRH is initialized to H'D0 by a power-on reset and in hardware standby mode. It is not
initialized by a manual reset or in software standby mode.
Bit 7—Idle Cycle Insert 1 (ICIS1): Selects whether or not one idle cycle state is to be inserted
between bus cycles when successive external read cycles are performed in different areas.
Bit 6—Idle Cycle Insert 0 (ICIS0): Selects whether or not one idle cycle state is to be inserted
between bus cycles when successive external read and external write cycles are performed.
