CGMXFC is an external filter capacitor connection for the CGM. See
Section 8. Clock Generator Module
Port A is a 7-bit special function port, sharing all of its pins with the
analog-to-digital converter (ADC). On the 32-pin QFP package, all seven
bits (PTA6/ATD6–PTA0/ATD0) of the port are available. On the 28-pin
package, four bits (PTA3/ATD3–PTA0/ATD0) are available.
PTA3–PTA0 have high current source and sink capability. See
