5.2.1
WSCR is an 8-bit readable/writable register that selects the wait mode for the wait-state controller
(WSC) and specifies the number of wait states. It also controls RAM area setting for dual-power-
supply flash memory, selection/non-selection of single-power-supply flash memory control
registers, and frequency division of the clock signals supplied to the supporting modules.
Notes: *1 These bits are valid only in the H8/3437F and H8/3434F (dual-power-supply on-chip
WSCR is initialized to H'08 by a reset and in hardware standby mode. It is not initialized in
software standby mode.
