The operation of the oscillator is controlled by three
Special Function Registers (SFRs):
• OSCCON
• CLKDIV
• OSCTUN
The OSCCON register (Register 9-1) is the main con-
trol register for the oscillator. It controls clock source
switching and allows the monitoring of clock sources.

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.

The Clock Divider register (Register 9-2) controls the
features associated with Doze mode, as well as the
postscaler for the FRC oscillator.
The FRC Oscillator Tune register (Register 9-3) allows
the user to fine tune the FRC oscillator over a range of
approximately ±12%. Each bit increment or decrement
changes the factory calibrated frequency of the FRC
oscillator by a fixed amount.
