Main Function

(after Reset)

Alternate Function

S Main power supply

I/O Timer input or output

I External clock input or resonator oscillator inverter input

O Resonator oscillator inverter output or resistor input for RC oscillator

I Non maskable interrupt (falling edge sensitive)

Must be held at Vss for normal operation, if a 12.5V level is applied to the pin

during the reset phase, the device enters EPROM programming mode.
