bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
q = depends on condition
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
IDLEN: Idle Enable bit
1
= Device enters Idle mode on SLEEP instruction
0
= Device enters Sleep mode on SLEEP instruction
bit 6-4
IRCF<2:0>: Internal RC Oscillator Frequency Select bits(2)
111
= HFINTOSC – (16 MHz)
110
= HFINTOSC/2 – (8 MHz)
101
= HFINTOSC/4 – (4 MHz)
100
= HFINTOSC/8 – (2 MHz)
011
= HFINTOSC/16 – (1 MHz)(3)
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)
bit 3
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)
bit 2
HFIOFS: HFINTOSC Frequency Stable bit
1
= HFINTOSC frequency is stable
0
= HFINTOSC frequency is not stable
bit 1-0
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).
Note 1:
Reset state depends on state of the IESO Configuration bit.
2:
INTOSC source may be determined by the INTSRC bit in OSCTUNE and the MFIOSEL bit in OSCCON2.
3:
Default output frequency of HFINTOSC on Reset.
