Please connect to GND.
I2C Slave address LSB setting
This terminal has pull-up resistor (300kΩTyp.) against VDD_IO built in.
When Open processed, slave address LSB becomes Hi.
Power supply input to drive sensor
Power supply input to drive serial interface. If its voltage differs from sensor drive power supply, please connect
interface power supply to this terminal. If the drive power supply is same, please short-circuit to VDD terminal.
