4 Clock System

The clock system of MSPM0C series contains the internal oscillators, the clock monitors, and the clock selection and control logic. A frequency clock counter is also provided for checking and/or calibrating the frenquency of high-speed clocks against a reference period/pluse provided on an IO pin. This section describes the clock resources on different MSPM0C family devices and their interaction with external signals or devices.
