design. The rate table is configured via the DLL and DLM internal register functions.
Customized Baud Rates can be achieved by selecting the proper divisor values for
the MSB and LSB sections of baud rate generator.
Programming the Baud Rate Generator Registers DLM (MSB) and DLL (LSB)
provides a user capability for selecting the desired final baud rate. The example in
