Section 12 Serial Communication Interface (SCI)
Table 12.5 shows the maximum bit rate for each frequency in asynchronous mode. Tables 12.6
and 12.7 show the maximum bit rates with external clock input.
When the ABCS bit in SCI0's serial expansion mode register 0 (SEMR0) is set to 1 in
asynchronous mode, the maximum bit rates are twice those shown in tables 12.5 and 12.6.
