Bits 3 and 2—Area 1 Wait Control 1 and 0 (W11, W10): These bits select the number of
program wait states when area 1 in external space is accessed while the AST1 bit in ASTCR is set
to 1.
Bits 1 and 0—Area 0 Wait Control 1 and 0 (W01, W00): These bits select the number of
program wait states when area 0 in external space is accessed while the AST0 bit in ASTCR is set
to 1.
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 areas 2 to 5 and 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.
