GND
Ground
2VREF/P0.4
Voltage Reference Input/Output or General-Purpose, Digital I/O, Type D Port. This pin functions as either
the output of the internal voltage reference or as a bidirectional I/O. This pin can also be driven with an external
voltage to provide an optional voltage reference. The pin defaults to a digital input with a weak pullup after a
reset.
3
CMP0/P0.3
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.
4
T2P/P0.2
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.
5
T2PB/P0.1
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.
6
P0.0
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.
7
P1.6
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.
8
P1.5
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.
9
TDO/P1.4
Debug Port Signal TDO or General-Purpose, Digital I/O, Type D Port. This pin functions as either the TDO
signal of the debug port or as a bidirectional I/O. The pin defaults to a digital input with a weak pullup after a reset.
10
TCK/P1.3
Debug Port Signal TCK or General-Purpose, Digital I/O, Type D Port. This pin functions as either the TCK signal
of the debug port or as a bidirectional I/O. The pin defaults to a digital input with a weak pullup after a reset.
11
HFXIN
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.
