UART Modules
26.3.4
The UCSRs select an external clock on the DTIN input (divided by 1 or 16) or a prescaled internal
bus clock as the clocking source for the transmitter and receiver. See
“Transmitter/Receiver Clock
sources. To use the internal bus clock for both, set UCSRn to 0xDD.
26.3.5
The UCRs, shown in
do not conflict can be specified in a single write to a UCRn. For example,
