19.3.4. External CMOS Clock Mode

If an external CMOS clock is used as the external oscillator, the clock should be directly routed into XTAL2.

The XTAL2 pin should be configured as a digital input. XTAL1 is not used in external CMOS clock mode.

The external oscillator valid detector will always return zero when the external oscillator is configured to

External CMOS Clock mode.
