Reset state depends on state of the IESO Configuration bit.
INTOSC source may be determined by the INTSRC bit in OSCTUNE and the MFIOSEL bit in OSCCON2.
Default output frequency of HFINTOSC 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 RC Oscillator Frequency Select bits
111 = HFINTOSC – (16 MHz)
110 = HFINTOSC/2 – (8 MHz)
101 = HFINTOSC/4 – (4 MHz)
100 = HFINTOSC/8 – (2 MHz)
011 = HFINTOSC/16 – (1 MHz)
If INTSRC = 0 and MFIOSEL = 0:
010 = HFINTOSC/32 – (500 kHz)
001 = HFINTOSC/64 – (250 kHz)
000 = LFINTOSC – (31.25 kHz)
If INTSRC = 1 and MFIOSEL = 0:
010 = HFINTOSC/32 – (500 kHz)
001 = HFINTOSC/64 – (250 kHz)
000 = HFINTOSC/512 – (31.25 kHz)
If INTSRC = 0 and MFIOSEL = 1:
010 = MFINTOSC – (500 kHz)
001 = MFINTOSC/2 – (250 kHz)
000 = LFINTOSC – (31.25 kHz)
If INTSRC = 1 and MFIOSEL = 1:
010 = MFINTOSC – (500 kHz)
001 = MFINTOSC/2 – (250 kHz)
000 = MFINTOSC/16 – (31.25 kHz)
OSTS: Oscillator Start-up Time-out Status bit
1 = Device is running from the clock defined by FOSC<3:0> of the CONFIG1H register
0 = Device is running from the internal oscillator (HFINTOSC, MFINTOSC or LFINTOSC)
HFIOFS: HFINTOSC Frequency Stable bit
1 = HFINTOSC frequency is stable
0 = HFINTOSC frequency is not stable
SCS<1:0>: System Clock Select bit
1x = Internal oscillator block
01 = Secondary (SOSC) oscillator
00 = Primary clock (determined by FOSC<3:0> in CONFIG1H).

OSCCON: OSCILLATOR CONTROL REGISTER
W = Writable bit
