Section 6 Bus Controller
6.2.3
WCRH and WCRL are 8-bit readable/writable registers that select the number of program wait
states for each area.
On-chip memory and registers are accessed in a fixed number of states that does not depend on
WCRH/WCRL settings.
WCRH and WCRL are initialized to H'FF by a reset and in hardware standby mode. They are not
initialized in software standby mode.
WCRH
Bit
Bits 7 and 6—Area 7 Wait Control 1 and 0 (W71, W70): These bits select the number of
program wait states when area 7 in external space is accessed while the AST7 bit in ASTCR is set
to 1.
