The addresses for this module seem to be 0x78 until 0x7F (depending on the address selection pins). You need to always write 1 byte (the address of the register), then read back two bytes for the register value. The datasheet goes into a lot of detail on the specifics of I2C, which are all already implemented by the IOIO software and that don't need to concern you at the application layer.
