11.3.4 RC Oscillator
The RC oscillator circuit is designed for use with an external resistor (R
a tolerance within 25% of the expected frequency. See
The capacitor (C) for the RC oscillator is internal to the MCU. The R

or less to minimize its effect on the frequency.
In this configuration, the OSC2 pin can be left in the reset state as PTA4. Or, the OSC2EN bit in the port
A pullup enable register can be set to enable the OSC2 output function on the pin. Enabling the OSC2
output slightly increases the external RC oscillator frequency, f

11.4 Oscillator Module Signals
The following paragraphs describe the signals that are inputs to and outputs from the oscillator module.
11.4.1 Crystal Amplifier Input Pin (OSC1)
The OSC1 pin is either an input to the crystal oscillator amplifier, an input to the RC oscillator circuit, or
an external clock source.
For the internal oscillator configuration, the OSC1 pin can assume other functions according to
Function Priority in Shared
Pins.
