Pin Description (continued)
PIN
NAME
FUNCTION
12
HFXOUT
Oscillator Output/Input. Connect an external crystal or resonator between HFXIN and HFXOUT as the system
clock. When using a crystal, a load capacitor of approximately 22pF must be connected between this pin and
ground. Alternatively, float HFXOUT when an external high-frequency clock source is connected to the HFXIN pin.
14,
16
N.C.
No Connection
17,
18
VDD
Digital Power. This pin should be connected to a bypass capacitor to ground.
19
TMS/P1.2
Debug Port Signal TMS or General-Purpose, Digital I/O, Type D Port. This pin functions as either the TMS
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.
20
RESET/P1.1
Active-Low Reset Input or General-Purpose, Digital I/O, Type D Port. This pin defaults to the reset input
mode of operation following a POR. The reset input mode can be deactivated and the digital I/O mode enabled
by programming the RSTD bit to 1.
21
TDI/P1.0
Debug Port Signal TDI or General-Purpose, Digital I/O, Type D Port. This pin functions as either the TDI 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.
22
LED/P0.7
High-Current (Sink) Driver Output or General-Purpose, Digital I/O, Type D Port. This pin functions with a
high-current pulldown to drive a device such as an LED or as a bidirectional I/O. The pin defaults to a digital
input with a weak pullup after a reset.
23
INT/P0.6
External Edge-Selectable Interrupt or General-Purpose, Digital I/O, Type D Port. This pin functions as
either an external edge-selectable interrupt or as a bidirectional I/O. The pin defaults to a digital input with a
weak pullup after a reset.
24
CMPI/P0.5
Analog Voltage Comparator Input or General-Purpose, Digital I/O, Type D Port. This pin functions as either
the input to the analog voltage comparator or as a bidirectional I/O. The pin defaults to a digital input with a
weak pullup after a reset.
