Bi-directional I/O port. Can be configured as T0CKI.
voltage input. When configured as MCLR, this pin is
an active low RESET to the device. Voltage on MCLR/
V
tion or the device will enter programming mode. Can
be software programmed for internal weak pull-up and
wake-up from SLEEP on pin change. Weak pull-up
always on if configured as MCLR. ST when in MCLR
mode.
Bi-directional I/O port/oscillator crystal output. Con-
nections to crystal or resonator in crystal oscillator
mode (XT and LP modes only, GPIO in other modes).
clock source input (GPIO in Internal RC mode only,
OSC1 in all other oscillator modes). TTL input when
GPIO, ST input in external RC oscillator mode.
Positive supply for logic and I/O pins
Ground reference for logic and I/O pins
Transmitter and CLKOUT enable. Internal pull-down.
Clock output.
Power select and ASK data input.
Positive supply for transmitter.
Antenna connection to differential power amplifier out-
put, open collector.
