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
11.4.2 Crystal Amplifier Output Pin (OSC2/PTA4/BUSCLKX4)
For the XTAL oscillator device, the OSC2 pin is the crystal oscillator inverting amplifier output.
For the external clock option, the OSC2 pin is dedicated to the PTA4 I/O function. The OSC2EN bit has
no effect.
For the internal oscillator or RC oscillator options, the OSC2 pin can assume other functions according to
