6.2.1 XTAL Oscillator
The XTAL oscillator circuit is designed for use with an external crystal or ceramic resonator to provide
accurate clock source.
In its typical configuration, the XTAL oscillator is connected in a Pierce oscillator configuration, as shown

OSCSEL selects the oscillator type for the MCU. The erased or unprogrammed state of this bit is
logic 1, selecting the crystal oscillator option. This bit is unaffected by reset.

When Crystal oscillator is selected, the OSC2/RCCLK/PTA6/KBI6 pin is
used as OSC2; other functions such as PTA6/KBI6 will not be available.
