I2C Address Register
The content of this register is irrelevant when I2C is in master mode. In the
slave mode, the seven most significant bits must be loaded with the MCU’s
own address. The I2C hardware will react if either of the address is
matched.
General Call Function
0 = Disable General Call Function.
1 = Enable General Call Function.
