GENERAL-PURPOSE I/O AND SPECIAL FUNCTION PINS
Supply Voltage
Regulator Capacitor. This pin must be connected to ground through a 1.0μF external
ceramic-chip capacitor in series with a 2 to 10 resistor. The capacitor must be
placed as close to this pin as
capacitor should be connected to this pin.
Ground. The GND contact is through the exposed paddle located on the underside of
the package. It must be directly connected to the ground plane.
Digital, Active-Low, Reset Input/Output. The CPU is held in reset when this pin is low
and begins executing from the reset vector when released. The pin includes pullup
current source and should be driven by an open-drain, external source capable of
sinking in excess of 4mA. This pin is driven low as an output when an internal reset
condition occurs.
High-Frequency Crystal Input. Connect external crystal or resonator between HFXIN
and HFXOUT as the high-frequency system clock. Alternatively, HFXIN is the input
for an external, high-frequency clock source when HFXOUT is floating.
IR Transmit Output. IR transmit pin capable of sinking 25mA. This pin defaults to
high-impedance input with the weak pullup disabled during all forms of reset.
Software must configure this pin after release from reset to remove the high-
impedance input condition.
IR Receive Input. IR receive pin. This pin defaults to high-impedance input with the
weak pullup disabled during all forms of reset. Software must configure this pin after
release from reset to remove the high-impedance input condition.
General-Purpose, Digital, I/O, Type-C Port. These port pins function as bidirectional
I/O pins. All port pins default to high-impedance mode after a reset. Software must
configure these pins after release from reset to remove the high-impedance input
condition. All alternate functions must be enabled from software.
