stores the data in a temporary register. If D register is
written first, and then the new data on data bus is stored in
D, the temporary value written by the last write to C3[T8]
gets stored in the C3[T8] register.

Reads return the contents of the read-only receive data register and writes go to the write-only transmit
data register.
38.4.9 UART Match Address Registers 1 (UARTx_MA1)
The MA1 and MA2 registers are compared to input data addresses when the most
significant bit is set and the associated C4[MAEN] field is set. If a match occurs, the
following data is transferred to the data register. If a match fails, the following data is
discarded. These registers can be read and written at anytime.
