11.1.2.4 LFINTOSC

The Low-Frequency Internal Oscillator (LFINTOSC) is a factory-calibrated 31 kHz internal clock source.

The LFINTOSC can be used as a system clock source, and may be used by certain peripheral modules as a clock source. Additionally, the LFINTOSC provides a time base for the following:

  • Power-up Timer (PWRT)
  • Watchdog Timer (WDT)

The LFINTOSC is enabled by programming the RSTOSC Configuration bits to select LFINTOSC.
