same system 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
Table 5 below, shows the selectable baud rate table
available when using a 1.8432 MHz external clock
input.
