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. It can be used to process tasks regularly, delay, output PWM waveforms to drive o devices, detect the width and frequency of external pulses, simulate waveform outputs, and more.

The MSPM0G series MCU includes three types of Timer module: TIMA, TIMG and TIMH. The advanced timer (TIMA), general-purpose timer (TIMG) and high-resolution timer (TIMH) are all timer counting modules 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. However, TIMA adds additional features such as complementary PWM with dead band insertion, and TIMH has a 24-bit resolution counter. A summary of the different features and configurations of each timer is shown in the following tables.

  • First look at the device specific data sheet to check which TIMG instances are available on the device
  • Need to check what features are available for each TIMG instance in Technical Reference Manual
