Reset state depends on state of the IESO Configuration bit.
Source selected by the INTSRC bit of the OSCTUNE register, see text.
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 Oscillator Frequency Select bits
111 = 16 MHz (HFINTOSC drives clock directly)
110 = 8 MHz
101 = 4 MHz
100 = 2 MHz
011 = 1 MHz
010 = 500 kHz
001 = 250 kHz
000 = 31 kHz (from either HFINTOSC/512 or LFINTOSC directly)
OSTS: Oscillator Start-up Time-out Status bit
1 = Device is running from the clock defined by FOSC<2:0> of the CONFIG1 register
0 = Device is running from the internal oscillator (HFINTOSC or LFINTOSC)
IOFS: HFINTOSC Frequency Stable bit
1 = HFINTOSC frequency is stable
0 = HFINTOSC frequency is not stable
SCS<1:0>: System Clock Select bits
1x = Internal oscillator block
01 = Secondary (Timer1) oscillator
00 = Primary clock (determined by CONFIG1H[FOSC<3:0>]).
