15. Low Power Oscillator and System Clock Generator
The source of all digital system clocks is derived from the low power oscillator (LPOSC) and system clock
generator. The LPOSC produces a 24 MHz clock signal and is used by the system clock generator to pro-
duce the system clock. This system clock is applied to all digital blocks including the MCU and is program-
mable via the SYSGEN SFR register which is useful for power savings. Users are recommended to use
the System Module Function API to set the registers.
