SDR0 is a 16-bit register that stores a remainder. This register stores 0 in the multiplication mode and the
remainder of an operation result in the division mode.
SDR0 can be read by an 8-bit or 16-bit memory manipulation instruction.
Reset signal generation clears SDR0 to 0000H.
MDA0 is a 32-bit register that sets a 16-bit multiplier A in the multiplication mode and a 32-bit dividend in the
division mode, and stores the 32-bit result of the operation (higher 16 bits: MDA0H, lower 16 bits: MDA0L).
Address: FF60H, FF61H

2. SDR0 is reset when the operation is started (when DMUE is set to 1).
2. Do not change the value of MDA0 during operation processing (while bit 7 (DMUE) of
3. The value read from MDA0 during operation processing (while DMUE is 1) is not guaranteed.

multiplier/divider control register 0 (DMUC0) is 1). Even in this case, the operation is executed,
but the result is undefined.
