18.5.3 Baudrate Selection and Calculation
Autobaud Detection requires some calculations concerning the programming of the
baudrate generator and the baudrates to be detected. Two steps must be considered:
• Defining the baudrate(s) to be detected
• Programming of the baudrate timer prescaler - setup of the clock rate of f_DIV
