Table 15.6 indicates the maximum bit rates in asynchronous mode when the baud rate generator is
used. Table 15.7 lists the maximum bit rates in asynchronous mode when the external clock input
is used. Table 15.8 lists the maximum bit rates in clock synchronous mode when the external
clock input is used (when t

Note: * Make sure that the electrical characteristics of this LSI and that of a connected LSI are
satisfied.
