weak pull-up and wake-up from Sleep on pin change.
Input port. 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.
weak pull-up and wake-up from Sleep on pin change.
Oscillator crystal output. Connections to crystal or resonator in
Crystal Oscillator mode (XT, HS and LP modes only).
configured for CLKOUT, which has 1/4 the frequency of OSC1
and denotes the instruction cycle rate.
Crystal input.
External clock source input.
Clock input to TMR0.
Positive supply for logic and I/O pins.
Ground reference for logic and I/O pins.
