• Initial setting
• During operation
• End of operation
• Next operation
1. Set operation data to multiplication/division data register A0L (MDA0L) and multiplication/division data register B0
2. Set bits 0 (DMUSEL0) and 7 (DMUE) of multiplier/divider control register 0 (DMUC0) to 1. Operation will start.
3. The operation will be completed when 16 peripheral hardware clocks (f
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.
7. To execute multiplication next, start from the initial setting in 19.4.1 Multiplication operation.
8. To execute division next, start from the initial setting in 19.4.2 Division operation.
