UARTnDR [7:0]
The UARTn Transmit Buffer and Receive Buffer share the same I/O
address with this DATA register. The Transmit Data Buffer is the
destination for data written to the UARTnDR register. Reading the
UARTnDR register returns the contents of the Receive Buffer.
Write this register only when the UDREn flag is set.
