Input Power supply: All V_CC pins should be
connected to the system power supply.
4 (= AV_SS)
55
12 (=
AV_SS)
63
Input
Ground: All V_SS pins should be
connected to the system power supply
(0 V).

Input Analog power supply: This is the
power supply pin for the A/D converter.
When the A/D converter is not used,
connect this pin to the system power
supply.
