These pins connect an oscillator to oscillate the X1 input clock.
X1 and X2 also function as the P121 and P122 pins, respectively. For settings of alternate function, refer to
Supply an external clock to X1.
Caution The P121/X1 and P122/X2 pins are pulled down during reset.
This is the A/D converter reference voltage input pin and the positive power supply pin of P20 to P23 and A/D
