Section 7 Bus Controller
7.2.4
BCRH is an 8-bit readable/writable register that selects enabling or disabling of idle cycle
insertion, and the memory interface for area 2 to 5, and 0.
BCRH is initialized to H'D0 by a reset and in hardware standby mode. It is not initialized 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 .
