THE OSCILLATOR MUST BE CONFIGURED IN ONE OF
THE FOLLOWING MODES:
– LOW FREQUENCY CRYSTAL
– MEDIUM FREQUENCY CRYSTAL
– HIGH FREQUENCY CRYSTAL
*
CAPACITOR VALUES MAY BE OPTIMIZED FOR
DIFFERENT OSCILLATOR FREQUENCIES (SEE TEXT)
A SERIES RESISTOR MAY BE REQUIRED IN ORDER TO
LIMIT CRYSTAL DRIVE LEVELS. THIS IS PARTICULARLY
IMPORTANT FOR LOW FREQUENCY CRYSTALS (SEE TEXT).

THE OSCILLATOR MUST BE CONFIGURED IN
THE EXTERNAL CLOCK INPUT MODE.
A CLOCK OUTPUT MAY BE OBTAINED ON
THE X2 PIN BY SETTING THE ENCLK BIT IN
THE P2M1 REGISTER.
