Analog Voltage Comparator Output or General-Purpose, Digital I/O, Type D Port. This pin functions as either
the output of the analog voltage comparator or as a bidirectional I/O. The pin defaults to a digital input with a
weak pullup after a reset.
Timer 2 Input/Output or General-Purpose, Digital I/O, Type D Port. This pin functions as either the input or
output of Timer 2 or as a bidirectional I/O. The pin defaults to a digital input with a weak pullup after a reset.
Secondary Timer 2 Input/Output or General-Purpose, Digital I/O, Type D Port. This pin functions as either the
secondary output of Timer 2 or as a bidirectional I/O. The pin defaults to a digital input with a weak pullup after a
reset.
General-Purpose, Digital I/O, Type D Port. This pin functions as a bidirectional I/O, and defaults to a digital
input with a weak pullup after a reset.

Oscillator Input. Connect an external crystal or resonator between HFXIN and HFXOUT for system clock
generation. When using a crystal, a load capacitor of approximately 22pF must be connected between this pin
and ground. Alternatively, HFXIN is the input for an external clock source when HFXOUT is floating.
