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.
