(5) Serial Data Reception (Synchronous Mode)
Figure 17.19 shows a sample flowchart for serial reception.
Use the following procedure for serial data reception after enabling the SCIF for reception.
When switching the operating mode from asynchronous mode to synchronous mode without
initializing the SCIF, make sure that the ORER, PER7 to PER0, and FER7 to FER0 flags are
cleared to 0.

identify any error, perform the
appropriate error handling, then clear
the ORER flag to 0.
Transmission/reception cannot be
resumed while the ORER flag is set
to 1.
read:
1, then read the receive data in
SCFRDR, and clear the RDF flag to
0. The transition of the RDF flag from
0 to 1 can also be identified by an
RXI interrupt.
procedure:
least the receive trigger set number
of receive data bytes from SCFRDR,
read 1 from the RDF flag, then clear
the RDF flag to 0. The number of
receive data bytes in SCFRDR can
be ascertained by reading SCRFDR.
