18.1 Functions of Multiplier/Divider
18.2 Configuration of Multiplier/Divider
Only for the
The multiplier/divider has the following functions.
• 16 bits × 16 bits = 32 bits (multiplication)
• 32 bits ÷ 16 bits = 32 bits, 16-bit remainder (division)
The multiplier/divider includes the following hardware.
Figure 18-1 shows the block diagram of the multiplier/divider.
Caution Do not use serial interface IIC0 and the multiplier/divider simultaneously, because various flags
corresponding to interrupt request sources are shared among serial interface IIC0 and the
multiplier/divider.
