Main Function
(after Reset)
Main power supply
External clock input or resonator oscillator inverter input
Resonator oscillator inverter output or resistor input for RC oscillator
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.
Top priority non maskable interrupt (active low)
