Low Frequency Clocks Scheme

LFXTAL and LFOSC can be the source for the LF_CLK mux. By default, LFOSC is selected as the source for this mux.

  • LF_CLK is used as the source clock for RTC1 and Beeper.
  • RTC0 is always sourced by the LFXTAL
  • WDT is always sourced by the LFOSC

Note that the LFXTAL should be enabled before changing the LF_CLK mux to 1.
