7.1 Timer Resources and Design Considerations

Timers are one of the most basic and important modules in any MCU, and this resource is used in all applications. Timers can be used to process tasks regularly, delay, output PWM waveforms to drive devices, detect the width and frequency of external pulses, simulate waveform outputs, and more.

The MSPM0C series MCU includes general-purpose timer (TIMG) and advanced control timers (TIMA). That can be used for a variety of functions, including measuring the input signal edge and period (capture mode) or generating output waveforms (compare mode output) like PWM signals. A summary of the different features and configurations of each timer is shown in the Table 7-1.
