8.2.2.1 HFINTOSC
The High-Frequency Internal Oscillator (HFINTOSC) is a precision digitally-controlled internal clock source that produces a stable clock up to 32 MHz. The HFINTOSC can be enabled through one of the following methods:
- Programming the RSTOSC bits in Configuration Word
1 to ‘
110’ (FOSC = 1 MHz) or ‘000’ (FOSC = 32 MHz) to set the oscillator upon device Power-up or Reset. - Write to the NOSC bits during run-time.
The HFINTOSC frequency can be selected by setting the HFFRQ bits.
The NDIV bits allow for division of the output of the selected clock source by a
range between 1:1 and 1:512.
