12.1.8.3 Baudrate Selection and Calculation
The 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
In general, the baudrate generator of the ASC in asynchronous mode is build up by two
parts (see also Figure 86) :
the clock prescaler part which derives f
the baudrate timer part which generates the sample clock f
