Name and Functions
Power supply: All V
should be connected to the user
system V
Ground: All V
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 V
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
oscillator, or can be used to input
an external clock.
See section 4, Clock Pulse
Generators, for a typical
connection diagram.
Subclock: These pins connect to
a 32.768-kHz crystal oscillator.
See section 4, Clock Pulse
Generators, for a typical
connection diagram.
Reset: When this pin is driven
low, the chip is reset
Test: This is a test pin, not for
use in application systems. It
should be connected to V
