CHAPTER 16 MULTIPLIER/DIVIDERUser’s Manual U16899EJ2V0UD 35316.4.2 Division operation• Initial setting1. Set operation data to multiplication/division data register A0 (MDA0L and MDA0H) and multiplication/divisiondata register B0 (MDB0).2. Set bits 0 (DMUSEL0) and 7 (DMUE) of multiplier/divider control register 0 (DMUC0) to 0 and 1, respectively.Operation will start.• During operation3. The operation will be completed when 32 internal clocks have been issued after the start of the operation(intermediate data is stored in the MDA0L and MDA0H registers and remainder data register 0 (SDR0) duringoperation, and therefore the read values of these registers are not guaranteed).• End of operation4. The result data is stored in the MDA0L, MDA0H, and SDR0 registers.5. DMUE is cleared to 0 (end of operation).6. After the operation, an interrupt request signal (INTDMU) is generated.• Next operation7. 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.
