Important: OSCTUNE tuning does not affect the LFINTOSC frequency.

11.2.2.1.2 MFINTOSC

The Medium-Frequency Internal Oscillator (MFINTOSC) generates two constant clock outputs (500 kHz and 31.25

kHz). The MFINTOSC clock signals are created from the HFINTOSC using dynamic divider logic, which provides

constant MFINTOSC clock rates regardless of selected HFINTOSC frequency.

The MFINTOSC cannot be used as the system clock, but can be used as a clock source for certain peripherals, such

as a Timer.

11.2.2.2 LFINTOSC

The Low-Frequency Internal Oscillator (LFINTOSC) is a factory-calibrated 31 kHz internal clock source.

The LFINTOSC can be used as a system clock source, and may be used by certain peripheral modules as a clock

source. Additionally, the LFINTOSC provides a time base for the following:

• Power-up Timer (PWRT)

• Watchdog Timer (WDT)

The LFINTOSC is enabled by programming the RSTOSC Configuration bits to select LFINTOSC.
