Function
RESET
A low level on this pin for the duration of
one machine cycle while the oscillator is
running resets the SAB 80C517A. A
small internal pull-up resistor permits
power-on reset using only a capacitor
connected to V
Reference voltage for the A/D con-
verter.
Reference ground for the A/D
converter.
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.
