CHAPTER 17 MULTIPLIER/DIVIDER
17.1 Functions of Multiplier/Divider
The multiplier/divider is mounted onto all 78K0R/Lx3 microcontroller products.
The multiplier/divider has the following functions.
• 16 bits × 16 bits = 32 bits (multiplication)
• 32 bits ÷ 32 bits = 32 bits, 32-bit remainder (division)
