Update: I found the datasheet and this is what they all mean but I could still use some help as to what I need to do with them.
VCC = Power supply voltage and Digital I/O supply voltage
GND = Power supply ground
SCL = 2C serial clock (SCL)
SDA = I 2C serial data (SDA)
XDA = For connecting external sensors
XCL = For connecting external sensors
ADD = I 2C Slave Address LSB (AD0)
INT = Interrupt digital output (totem pole or open-drain)
