Register 16: I
2
C Slave Data (I2CSDR), offset 0x808
Important: This register is read-sensitive. See the register description for details.
This register contains the data to be transmitted when in the Slave Transmit state, and the data
received when in the Slave Receive state. If the RXFIFO bit or TXFIFO bit are enabled in the
I2CSCSR register, then this register is ignored and the data value being transferred from the FIFO
is contained in the I2CFIFODATA register.
Note: Best practice recommends that an application should not switch between the I2CSDR
register and TX FIFO or vice versa for successive transactions.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
