Analog input pin. This signal goes to a programmable
comparator and is used to sense the value of an external
voltage.

RESET

I
Reset input, positive assertion. Resets logic and registers
to default condition. Note: to insure proper reset operation
after VDD is turned on by application of VBUS power or
activation of the ON/OFF switch, external reset circuitry
must generate a proper reset signal to the 73S1210F. This
can be accomplished via a simple RC network.
