2:
Depends on the state of the IESO bit in Configuration Register 1H.
Default output frequency of INTOSC on Reset.
IDLEN: Idle Enable bit
1 = Idle mode enabled; CPU core is not clocked in power-managed modes
0 = Run mode enabled; CPU core is clocked in power-managed modes
IRCF<2:0>: Internal Oscillator Frequency Select bits
111 = 8 MHz (8 MHz source drives clock directly)
110 = 4 MHz (default)
101 = 2 MHz
100 = 1 MHz
011 = 500 kHz
010 = 250 kHz
001 = 125 kHz
000 = 31 kHz (INTRC source drives clock directly)
OSTS: Oscillator Start-up Timer Time-out Status bit
1 = Oscillator Start-up Timer time-out has expired; primary oscillator is running
0 = Oscillator Start-up Timer time-out is running; primary oscillator is not ready
IOFS: INTOSC Frequency Stable bit
1 = INTOSC frequency is stable
0 = INTOSC frequency is not stable
