Section 15 Serial Communication Interface with FIFO (SCIF)
Table 15.6 indicates the maximum bit rates in asynchronous mode when the baud rate generator is
used. Tables 15.7 and 15.8 list the maximum bit rates when the external clock input is used.
Note: * Make sure that the electrical characteristics of this LSI and that of a connected LSI are
satisfied.
