Control Registers
The OSCCON register (Register 3-1) controls the main
aspects of the device clock’s operation. It selects the
oscillator type to be used, which of the power-managed
modes to invoke and the output frequency of the
INTOSC source. It also provides status on the oscillators.
The OSCTUNE register (Register 3-2) controls the
tuning and operation of the internal oscillator block. It
also implements the PLLEN bits which control the
operation of the Phase Locked Loop (PLL) (see
REGISTER 3-1:

bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-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 an Idle mode when a SLEEP instruction is executed
0
= Device enters Sleep mode when a SLEEP instruction is executed
bit 6-4
IRCF<2:0>: INTOSC Source Frequency Select bits(2)
111
= 8 MHz (INTOSC drives clock directly)
110
= 4 MHz (default)
101
= 2 MHz
100
= 1 MHz
011
= 500 kHz
010
= 250 kHz
001
= 125 kHz
000
= 31 kHz (from either INTOSC/256 or INTRC)(3)
bit 3
OSTS: Oscillator Start-up Timer Time-out Status bit(1)
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
bit 2
IOFS: INTOSC Frequency Stable bit
1
= Fast RC oscillator frequency is stable
0
= Fast RC oscillator frequency is not stable
bit 1-0
SCS<1:0>: System Clock Select bits(4)
11
= Internal oscillator block
10
= Primary oscillator
01
= Timer1 oscillator
00
= Default primary oscillator (as defined by the FOSC<2:0> Configuration bits)
Note 1:
Reset state depends on the state of the IESO Configuration bit.
2:
Modifying these bits will cause an immediate clock frequency switch if the internal oscillator is providing
the device clocks.
3:
Source selected by the INTSRC bit (OSCTUNE<7>), see text.
4:
Modifying these bits will cause an immediate clock source switch.
