Function Description DC/DC voltage converter. Connect a capacitor between this terminal and VIN when the built-in booster is used. For voltage booster circuit(VDD-VSS) External capacitor about 0.1u~4.7uf Power supply GND (In I2C interface DB7 (SDA) is input data. SDA and SCL must connect to I2C bus (I2C bus is to connect a resister between SDA/SCL and the power of I2C bus). (In I2C interface DB6 (SCL) is clock input. SDA and SCL must connect to I2C bus (I2C bus is to connect a resister between SDA/SCL and the power of I2C bus). RESET
