Table 22.6 indicates the maximum bit rates in asynchronous mode when the baud rate generator is
used. Table 22.7 lists the maximum bit rates in asynchronous mode when the external clock input
is used. Table 22.8 lists the maximum bit rates in clocked synchronous mode when the external
clock input is used (when t_Scyc = 12t_pcyc*).
Note: * Make sure that the electrical characteristics of this LSI and that of a connected LSI are
satisfied.
