Ground pin. Connect this pin to the
system power supply (0V).
Analog power supply pin for the A/D
converter. When the A/D converter
is not used, connect this pin to the
system power supply.
Internal step-down power supply
pin. Connect a capacitor of around
0.1 F between this pin and the Vss
pin for stabilization.
These pins connect to a crystal or
ceramic resonator for system
clocks, or can be used to input an
external clock.
See section 5, Clock Pulse
Generators, for a typical
connection.
Reset pin. When this driven low, the
chip is reset.
Test pin. Connect this pin to Vss.
Non-maskable interrupt request
input pin.
External interrupt request input
pins. Can select the rising or falling
edge.
