16.4 Operations of Multiplier/Divider
16.4.1 Multiplication operation
• Initial setting
1. Set operation data to multiplication/division data register A0L (MDA0L) and multiplication/division data register
B0 (MDB0).
2. Set bits 0 (DMUSEL0) and 7 (DMUE) of multiplier/divider control register 0 (DMUC0) to 1. Operation will start.
• During operation
3. The operation will be completed when 16 internal clocks have been issued after the start of the operation
(intermediate data is stored in the MDA0L and MDA0H registers during operation, and therefore the read
values of these registers are not guaranteed).
• End of operation
4. The operation result data is stored in the MDA0L and MDA0H registers.
5. DMUE is cleared to 0 (end of operation).
6. After the operation, an interrupt request signal (INTDMU) is generated.
• Next operation
7. To execute multiplication next, start from the initial setting in 16.4.1 Multiplication operation.
8. To execute division next, start from the initial setting in 16.4.2 Division operation.
