Section 13 Serial Communication Interface (SCI)
Figure 13-17 Example of SCI Operation in Transmission
Serial data reception (clocked synchronous mode)
Figure 13-18 shows a sample flowchart for serial reception.
The following procedure should be used for serial data reception.
When changing the operating mode from asynchronous to clocked synchronous, be sure to
check that the ORER, PER, and FER flags are all cleared to 0.
The RDRF flag will not be set if the FER or PER flag is set to 1, and neither transmit nor
receive operations will be possible.
