Functions
Power supply pin. Connect this pin to the
system power supply.
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 µF between this pin and
the Vss pin for stabilization.
These pins connect with crystal or ceramic
resonator for the system clock, or can be used
to input an external clock.
See section 5, Clock Pulse Generators, for a
typical connection.
These pins connect with a 32.768 kHz crystal
resonator for the subclock. 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. Be
sure to pull-up by a pull-up resistor.
External interrupt request input pins. Can select
the rising or falling edge.
External interrupt request input pins. Can select
the rising or falling edge.
This is an output pin for divided clocks.
This is an output pin for waveforms generated
by the output compare function.
External event input pin.
Counter reset input pin.
Counter start trigger input pin.
