(2) Multiplication input data registers A, B (MULA, MULB)
register (MULOH, MULOL)
These two registers, MULOH and MULOL, are used to store a 32-bit multiplication result. The higher 16 bits
of the multiplication result are stored in MULOH and the lower 16 bits, in MULOL, so that a total of 32 bits of
the multiplication result can be stored.
These registers hold the result of multiplication after the lapse of one CPU clock.
MULOH and MULOL can be read by a 16-bit memory manipulation instruction.
Reset signal generation clears these registers to 0000H.
These are 16-bit registers that store data for multiplication. The multiplier multiplies the values of MULA and
MULB.
MULA and MULB can be set by a 16-bit memory manipulation instruction.
Reset signal generation clears these registers to 0000H.
