6.1.2
WSCR is an 8-bit readable/writable register that controls frequency division of the clock signals
supplied to the supporting modules. It also controls wait state controller wait settings, RAM area
setting for dual-power-supply flash memory, and selection/non-selection of single-power-supply
flash memory control registers.
WSCR is initialized to H'08 by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Notes: *1 These bits are valid only in the H8/3437F and H8/3434F (dual-power-supply on-chip
Bit 7—RAM Select (RAMS)
Bit 6—RAM Area Select (RAM0)
Bits 7 and 6 select a RAM area for emulation of dual-power-supply flash memory updates. For
details, see the flash memory description in section 19, 20, ROM.
Bit 5—Clock Double (CKDBL): Controls the frequency division of clock signals supplied to
supporting modules.

Bit 4—Flash Memory Control Register Enable (FLSHE): Controls selection/non-selection of
single-power-supply flash memory control registers. For details, see the description of flash
memory in section 21, ROM. In models other than the H8/3437SF, this bit is reserved, but it can
be written and read; its initial value is 0.
Bits 3 and 2—Wait Mode Select 1 and 0 (WMS1/0)
Bits 1 and 0—Wait Count 1 and 0 (WC1/0)
These bits control wait-state insertion. For details, see section 5, Wait-State Controller.
