RESET
A low level on this pin for the duration of two
machine cycles while the oscillator is
running resets the C517A. A small internal
pullup resistor permits power-on reset using
only a capacitor connected to V

Port 7
is an 8-bit unidirectional input port. Port pins
can be used for digital input, if voltage levels
meet the specified input high/low voltages,
and for the lower 8-bit of the multiplexed
analog inputs of the A/D converter,
simultaneously.
