011111 = Center frequency +12.5%

Note 1: OSCTUN functionality has been provided to help customers compensate for temperature effects on the

FRC frequency over a wide range of temperatures. The tuning step size is an approximation, and is neither

characterized, nor tested.

Note: Writes to this register require an unlock sequence. Refer to Section 6. “Oscillator” (DS60001112) in the

“PIC32 Family Reference Manual” for details.
