8.2.2.5 LFINTOSC
The Low-Frequency Internal Oscillator (LFINTOSC) is a factory-calibrated 31 kHz internal clock source.
The LFINTOSC is the frequency for the Power-up Timer (PWRT), Windowed Watchdog Timer (WWDT) and Fail-Safe Clock Monitor (FSCM).
The LFINTOSC is enabled through one of the following methods:
- Programming the RSTOSC bits of Configuration Word 1 to enable LFINTOSC.
- Write to the NOSC bits during run-time.
