14.3.5 UART Command Registers (UCRn)
The UART command registers (UCRn), Figure 14-6, supply commands to the UART. Only
multiple commands that do not conflict can be specified in a single write to a UCRn. For
example,
command.
Table 14-6 describes UCRn fields and commands. Examples in Section 14.5.2,
“Transmitter and Receiver Operating Modes,” show how these commands are used.
