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 sourrces. For details, see the device-specific data sheet.
Type | STM8L | STM8S | MSPM0L | MSPM0C | |

Internal oscillators | High Speed | HSI: internal 16-MHz RC oscillator | HSI: internal 16-MHz RC oscillator | SYSOSC: internal oscillator from 4 MHz to 32 MHz |
SYSOSC : internal 24-MHz oscillator |
Low Speed | LSI: internal 38-kHz RC oscillator | LSI: internal 128-kHz RC oscillator | LFOSC: internal 32-kHz oscillator | LFOSC: internal 32-kHz oscillator | |
