weak pull-up and wake-up from Sleep on pin change.
Clock input to TMR0.
Input pin. Can be software programmed for internal weak
pull-up and wake-up from Sleep on pin change.
Master Clear (Reset). When configured as MCLR, this pin is
an active-low Reset to the device. Voltage on MCLR/V
not exceed V
will enter Programming mode. Weak pull-up always on if
configured as MCLR.
Programming voltage input.
Oscillator crystal output. Connections to crystal or resonator in
Crystal Oscillator mode (XT and LP modes only, GPIO in other
modes).
Oscillator crystal input.
External clock source input.
Positive supply for logic and I/O pins.
Ground reference for logic and I/O pins.
