Functions
Power supply pin. Connect this pin
to the system power supply.
Ground pin. Connect this pin to the
system power supply (0 V).
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 µF between this pin and the Vss
pin for stabilization.
These pins are connected to a
crystal or ceramic resonator for
system clocks, or can be used to
input an external clock. When an
internal RC oscillator is used,
system clocks can be output to
OSC2. See section 5, Clock Pulse
Generators, for a typical
connection.
Reset pin. The pull-up resistor (typ.
150 kΩ) is incorporated. When
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 pin.
Can select the rising or falling edge.
