Data Register
The Data register contains the transmission data/slave address or the receipt data byte.
In transmit mode, the byte is sent most-significant bits first.
In receive mode, the first bit received is placed in the register’s most-significant bits.
After each byte transmits, the Data register contains the byte present on the bus; therefore, if
arbitration is lost, the Data register has the correct receive byte.
