PIC16(L)F18425/45

8.3 Clock Switching

The system clock source can be switched between external and internal clock sources via software using the New Oscillator Source (NOSC) and New Divider selection request (NDIV) bits. The following clock sources can be selected:

External Oscillator (EXTOSC)
High-Frequency Internal Oscillator (HFINTOSC)
Low-Frequency Internal Oscillator (LFINTOSC)
Secondary Oscillator (SOSC)
EXTOSC with 4x PLL
HFINTOSC with 2x PLL
