15.6.6
The SCIF operates on a base clock with a frequency of 16 times the transfer rate. In reception, the
SCIF synchronizes internally with the fall of the start bit, which it samples on the base clock.
Receive data is latched at the rising edge of the eighth base clock pulse.* The timing is shown in
figure 15.17.
Note: * This is an example when ABCS = 0 in SCSEMR. When ABCS = 1, a frequency of 8 times
