FAQ's

Is it possible to externally input the 32.768 kHz clock to XT0 or XT1 of the crystal oscillator connection pin to activate it?
- Yes. Please follow the instructions below:
  - Input the external clock from XT0.
  - Set the voltage of the external clock at approximately 0.6 V.
  　*Current consumption may increase if a voltage higher than 0.6 V is input.
  　*Connect a coupling capacitor each between the external clock and XT0, and between XT0 and GND to decrease the voltage if the voltage of the external clock is high.
