Depends on state of the IESO Configuration bit.
Source selected by the INTSRC bit (OSCTUNE<7>), see text.
Default output frequency of INTOSC on Reset.
IDLEN: Idle Enable bit
1 = Device enters Idle mode on SLEEP instruction
0 = Device enters Sleep mode on SLEEP instruction
IRCF<2:0>: Internal Oscillator Frequency Select bits
111 = 8 MHz (INTOSC drives clock directly)
110 = 4 MHz
101 = 2 MHz
100 = 1 MHz
011 = 500 kHz
010 = 250 kHz
001 = 125 kHz
000 = 31 kHz (from either INTOSC/256 or INTRC 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 and the frequency is provided by one of the RC modes
0 = INTOSC frequency is not stable
SCS<1:0>: System Clock Select bits
1x = Internal oscillator block
01 = Timer1 oscillator
00 = Primary oscillator
