I
RESET
A low level on this pin for the duration of two machine
cycles while the oscillator is running resets the C515. A
small internal pullup resistor permits power-on reset
using only a capacitor connected to V_SS .
– Reference voltage for the A/D converter
– Reference ground for the A/D converter

Port 6
is an 8-bit unidirectional input port to the A/D converter.
Port pins can be used for digital input, if voltage levels
simultaneously meet the specifications for high/low input
voltages and for the eight multiplexed analog inputs.
