STM8 and MSPM0 devices have many types of clock sources including both internal and external for low system cost and low power consumption. Table 3-6 lists the different clock sources in STM8 and MSPM0 devices. Note that not all the devices have all types clock sources. For details, refer to the device-specific data sheet.
