12.3 Multiplier Control Register
222
Address: FFD2H After reset: 00H RW
The multiplier is controlled by the following register.
(1) Multiplier control register 0 (MULC0)
MULC0
Symbol
Multiplier control register 0 (MULC0)
This register indicates the operating status of the multiplier after operation, as well as controls the multiplier.
MULC0 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
