Functions
Power supply pin. Connect this pin
to the system power supply.
Ground pin. Connect all these pins
to the system power supply(0V).
Analog power supply pin for the A/D
converter. When the A/D converter
is not used, connect all this pin to
the system power supply.
Internal step-down power supply
pin. Connect a capacitor of around
0.1µF between this pin and the Vss
pin for stabilization.
These pins connect to a crystal or
ceramic oscillator for system clocks,
or can be used to input an external
clock.
These pins 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.
External interrupt request input
pins. Can select the rising or falling
edge.
