Oscillator Control
The Oscillator Control (OSCCON) register (Figure 3-1)
controls the system clock and frequency selection
options. The OSCCON register contains the following
bits:
Frequency selection bits (IRCF)
Frequency Status bits (HTS, LTS)
System clock control bits (OSTS, SCS)

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
Unimplemented: Read as ‘0’

000
= 31 kHz (LFINTOSC)
bit 3
OSTS: Oscillator Start-up Time-out Status bit(1)
1
= Device is running from the external clock defined by FOSC<2:0> of the Configuration Word register
0
= Device is running from the internal oscillator (HFINTOSC or LFINTOSC)
bit 2
HTS: HFINTOSC Status bit (High Frequency – 8 MHz to 125 kHz)
1
= HFINTOSC is stable
0
= HFINTOSC is not stable
bit 1
LTS: LFINTOSC Stable bit (Low Frequency – 31 kHz)
1
= LFINTOSC is stable
0
= LFINTOSC is not stable
bit 0
SCS: System Clock Select bit
1
= Internal oscillator is used for system clock
0
= Clock source defined by FOSC<2:0> of the Configuration Word register
Note 1:
Bit resets to ‘0’ with Two-Speed Start-up and LP, XT or HS selected as the Oscillator mode or Fail-Safe
mode is enabled.
