DUART
Except for the case when there is an overrun, URBR returns the data in the order it was received from the
transmitter. Refer to the ULSR[OE] description,

18.3.1.2
A write to these 8-bit registers causes the UART devices to transfer 5 to 8 data bits on the UART bus in
the format set up in the ULCR (line control register). In FIFO mode, data written to UTHR is placed into
the FIFO. The data written to UTHR is the data sent onto the UART bus, and the first byte written to UTHR
is the first byte onto the bus. UDSR[TXRDY] indicates when the FIFO is full. Refer to

18.3.1.3
UDLB is concatenated with the divisor most significant byte register (UDMB) to create the divisor used
to divide the input clock into the DUART. The output frequency of the baud generator is 16 times the baud
rate; therefore, the desired baud rate = platform clock frequency ÷ (16 × [UDMB||UDLB]). Equivalently,
