I

RESET

A low level on this pin for the duration of one machine

cycle while the oscillator is running resets the C509-L. 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

Port 7

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.
