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 frequency division of clock signals supplied to
supporting modules. For details, see section 6, Clock Pulse Generator.
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.
