Functions
Power supply pin. Connect this pin to the
system power supply.
Ground pin. Ensure to connect all pins 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.
Analog ground pin for the A/D converter.
Connect this pin to the system power
supply
(0 V).
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.
When using the on-chip oscillator, the
system clock can be output from OSC2
pin.
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.
