9.3
The operation of the oscillator is controlled by three
Special Function Registers (SFRs):
• OSCCON
• CLKDIV
• OSCTUN
The OSCCON register
control register for the oscillator. It controls clock
source switching and allows the monitoring of clock
sources.

Control Registers
Reset values for these bits are determined by the FNOSC Configuration bits.
Also resets to ‘0’ during any valid clock switch or whenever a non-PLL Clock mode is selected.
When SOSC is selected to run from a digital clock input, rather than an external crystal (SOSCSRC = 0),
this bit has no effect.

The Clock Divider register
features associated with Doze mode, as well as the
postscaler for the FRC oscillator.
The FRC Oscillator Tune register
the user to fine tune the FRC oscillator over a range of
approximately ±5.25%. Each bit increment or decre-
ment changes the factory calibrated frequency of the
FRC oscillator by a fixed amount.
