Name and Functions
Power supply: All V
connected to the system power supply.
Ground: All V
to the system power supply (0 V).
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.
Analog ground: This is the A/D converter
ground pin. It should be connected to the
system power supply (0V).
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.
These pins connect to a 76.8-kHz or
160-kHz crystal oscillator. Output See
section 4, Clock Pulse Generators, for a
typical connection diagram.
Reset: When this pin is driven low, the chip
is reset
Reset output: Outputs the CPU internal
reset signal.
