Description
Analog input pin. This signal goes to a programmable
comparator and is used to sense the value of an
external voltage.
Input pin for use in programming security fuse. It
should be connected to ground when not in use.
Test pin, should be connected to ground.
General positive power supply pins. All digital IO is
referred to this supply voltage. There is an on-chip
regulator that uses VDD to provide power for internal
circuits (VPD). A 0.1μF capacitor is recommended at
each VDD pin.
No connect.
General ground supply pins for all IO and logic circuits.
Reset input, positive assertion. Resets logic and
registers to default condition.
