In asynchronous mode, the SCI performs synchronization at the falling edge of the start bit in
reception. The SCI samples the data on the eighth pulse of a clock with a frequency of 16 times
the length of one bit, so that the transfer data is latched at the center of each bit.
Data Transfer Format
Table 15.10 shows the data transfer formats that can be used in asynchronous mode. Any of 12
transfer formats can be selected according to the SCSMR1 setting.
