Description
Power supply pin. Connect it to the system power supply. Connect this pin
to VSS by a 0.1-μF capacitor. The capacitor should be placed close to the
pin.
Connect this pin to the VSS pin by the smoothing capacitor used to stabilize
the internal power supply. Place the capacitor close to the pin.
Ground pin. Connect it to the system power supply (0 V).
Pins for a crystal resonator. An external clock signal can be input through
the EXTAL pin.
Input/output pins for the sub-clock oscillator. Connect a crystal resonator
between XCOUT and XCIN.
Clock output pin
Pins for setting the operating mode. The signal levels on these pins must
not be changed during operation mode transition at the time of release from
the reset state.
Reset signal input pin. The MCU enters the reset state when this signal
goes low.
Measurement reference clock input pin
Serial wire debug data input/output pin
Serial wire clock pin
Non-maskable interrupt request pin
Maskable interrupt request pins
External trigger input pin
Input capture, output compare, or PWM output pin
