Table 15.4 lists the sample SCBRR settings in asynchronous mode in which a base clock
frequency is 16 times the bit rate (the ABCS bit in SCEMR is 0) and the baud rate generator
operates in normal mode (the BGDM bit in SCEMR is 1), and table 15.5 lists the sample SCBRR
settings in clock synchronous mode.
