bit 1-0
OSCCON: OSCILLATOR CONTROL REGISTER
bit 7
IDLEN: Idle Enable bit
1 = Device enters an Idle mode when a SLEEP instruction is executed
0 = Device enters Sleep mode when a SLEEP instruction is executed
IRCF2:IRCF0: 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 Time-out Status bit
1 = Oscillator Start-up Timer (OST) time-out has expired; primary oscillator is running
0 = Oscillator Start-up Timer (OST) 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
SCS1:SCS0: System Clock Select bits
1x = Internal oscillator block
01 = Secondary (Timer1) oscillator
00 = Primary oscillator
Legend:
R = Readable bit
-n = Value at POR
IDLEN
R/W-0
Note 1: Reset state depends on state of the IESO configuration bit.
2: Source selected by the INTSRC bit (OSCTUNE<7>), see text.
3: Default output frequency of INTOSC on Reset.
4: Modifying the SCSI:SCSO bits will cause an immediate clock source switch.
5: Modifying the IRCF3:IRCF0 bits will cause an immediate clock frequency switch if
the internal oscillator is providing the device clocks.
