This register disables I²C bus interface. I²C bus interface is enabled in default. To disable I²C bus interface,
write “00011011” to I2CDIS register. Then I²C bus interface is disabled.
Once I²C bus interface is disabled, it is impossible to write other value to I2CDIS register. To enable I²C bus
interface, reset AK8963 or input start condition 8 times continuously.
