8.6.2 OSCCON2

Oscillator Control Register 2
Note:
  1. The POR value is the value present when user code execution begins.
  2. The Reset value (n) is the same as the OSCCON1[NOSC/NDIV] bits.
  3. EXTOSC configured by the CONFIG1[FEXTOSC] bits.
  4. HFINTOSC frequency is configured with the FRQ bits of the OSCFRQ register.
