User manual
13.5.15.1 Baud rate calculation
UART can operate with or without using the Fractional Divider. In real-life applications it is
likely that the desired baud rate can be achieved using several different Fractional Divider
settings. The following algorithm illustrates one way of finding a set of DLM, DLL,
MULVAL, and DIVADDVAL values. Such set of parameters yields a baud rate with a
relative error of less than 1.1% from the desired one.
