16.3 Register Controlling Multiplier and Divider/Multiply-Accumulator
The multiplier and divider/multiply-accumulator is controlled by using the multiplication/division control register (MDUC).
16.3.1 Multiplication/division control register (MDUC)
The MDUC register is an 8-bit register that controls the operation of the multiplier and divider/multiply-accumulator.
The MDUC register can be set by a 1-bit or 8-bit memory manipulation instruction.
Note that the overflow flag (MACOF) and sign flag (MACSF) of the multiply-accumulation result (accumulated) are
read-only flags.
Reset signal generation clears this register to 00H.
