— Active-low Reset to device. Voltage on the MCLR/VPP pin must
not exceed VDD to avoid unintended entering of Programming
mode.
— Programming voltage input
— Oscillator crystal input
— External clock source input
XTAL Oscillator crystal output. Connects to crystal or resonator in
Crystal Oscillator mode.
CMOS In RC mode, OSC2 pin outputs CLKOUT, which has 1/4 the
frequency of OSC1.
— Positive supply for logic and I/O pins
— Ground reference for logic and I/O pins
— Unused, do not connect
I/O = input/output
— = Not Used
TTL = TTL input
CMOS = CMOS output
XTAL = Crystal input/output
HV = High Voltage
