Name and Functions
Power supply: All VCC pins
should be connected to the user
system VCC.
Ground: All VSS pins should be
connected to the user system
GND.
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 user system VCC.
Analog ground: This is the A/D
converter ground pin. It should be
connected to the user system
GND.
System clock: These pins
connect to a crystal or ceramic
resonator, or can be used to input
an external clock.
See section 4, Clock Pulse
Generators, for a typical
connection diagram.
