2.2.2 Use ADC Detect High and Low

All of MSPM0 has ADC and multi-input channels, and can be used for 0% or 100% duty cycle high or low detection. The internal connection can be connected as shown in the demo code.

ADC Implementation Interconnection in the Demo Figure 2-5 ADC Implementation Interconnection in the Demo

Do not use additional pins for detection in the implementation. The ADC channel shares the same input pin with TIMER1 capture input. This needs the PWM capture pin to share the function of the capture and ADC input of the timer.
