Z32F0641 Product Specification
Motor Pulse Width Modulator
MP0.IER[5:0] control bits are shared by duty match interrupt event and ADC trigger match interrupt event.
When ADC trigger mode is disabled, the interrupt is generated by the duty match condition. In other cases,
the interrupt is generated by the ADC trigger counter match condition. The ADC trigger mode is selected by
the ATMOD bit field in the ATRm register.
MP0.SR MPWM Status Register
The PWM Status Register is a 16-bit register.
MP0.SR=0x4000_4030
