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

The MSPM0H series MCU includes two types of timer modules: advanced timer (TIMA) and general-purpose timer (TIMG). The TIMA and TIMG are 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. A summary of the different features and configurations of each timer is shown in Table 7-1 and Table 7-2.
