Section 14 Serial Communication Interface (SCI)
Serial data reception (synchronous mode): Figure 14.18 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 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.
