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 VSS .

– Reference voltage for the A/D converter

– Reference ground for the A/D converter

I

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.
