9.2.4 READ (Command Description)

Figure 16. Full Read Command

9.2.5 Baud-rate Automatic Detection

The UART includes a built-in baud-rate monitor that uses the synchronization frame to detect the external controller baud-rate. This baud-rate is

used after the synchronization byte to decode the following frame and to transmit the answer and it is stored in the BAUDREG register.

9.2.6 Baud-rate Manual Setting (optional)

The BAUDREG register can be read and over-written for a possible manual setting of the baud-rate: in case the register is overwritten with a

value different from 0, this value will be used for the following UART communications and the synchronization frame must be removed from the

request.
