18.3 Register Controlling Multiplier/Divider
CHAPTER 18 MULTIPLIER/DIVIDER ( PD78F0374, 78F0375, 78F0376, 78F0376D, 78F0384, 78F0385, 78F0386, AND 78F0386D ONLY)
Address: FF68H
The multiplier/divider is controlled by multiplier/divider control register 0 (DMUC0).

DMUC0 is an 8-bit register that controls the operation of the multiplier/divider.
DMUC0 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets DMUC0 to 00H.
