D, PW 1 A0 Address input 0. Connect directly to VCC or ground. 2 A1 Address input 1. Connect directly to VCC or ground. 3 RESET Active-low reset input. Connect to VCC or VDPUM (1) through a pull-up resistor, if not used. 4 INT0 Active-low interrupt input 0. Connect to VDPU0 (1) through a pull-up resistor. 5 SD0 Serial data 0. Connect to VDPU0 (1) through a pull-up resistor. 6 SC0 Serial clock 0. Connect to VDPU0 (1) through a pull-up resistor. 7 GND Ground 8 INT1 Active-low interrupt input 1. Connect to VDPU1 (1) through a pull-up resistor. 9 SD1 Serial data 1. Connect to VDPU1 (1) through a pull-up resistor. 10 SC1 Serial clock 1. Connect to VDPU1 (1) through a pull-up resistor. 11 INT Active-low interrupt output. Connect to VDPUM (1) through a pull-up resistor. 12 SCL Serial clock line. Connect to VDPUM (1) through a pull-up resistor. 13 SDA Serial data line. Connect to VDPUM (1) through a pull-up resistor. 14 VCC Supply power (1) VDPUX is the pull-up reference voltage for the associated data line. VDPUM is the master I 2C reference voltage while V DPU0 and VDPU1 are the slave channel reference voltages.
