SCIF initialization: See figure 16.3, Sample
SCIF Initialization Flowchart.
SCIF status check and receive data write:
Read SCFSR, check that the TDFE flag is
set to 1, then write transmit data in SCFTDR
and clear the TDFE flag to 0. Notification that
the TDFE flag has changed from 0 to 1 can
also be given by the TXI.
Receive error handling: If a receive error occurs,
read the ORER flag in SCLSR, then after
executing the necessary error handling, clear
the ORER flag to 0. Serial reception cannot be
continued while the ORER flag is set to 1.
SCIF status check and receive data read:
Read SCFSR, check that the RDF flag is set
to 1, then read receive data from SCFRDR
and clear the RDF flag to 0. Notification that
the RDF flag has changed from 0 to 1 can also
be given by the RXI.
Serial transmission/reception continuation
procedure: To continue serial reception, before
the MSB of the current frame is received, read
the RDF flag and SCFRDR and clear the RDF
flag to 0. Also, check that the TDFE flag is set
to 1 and data can be written before transmitting
the MSB of the current frame. Futhermore, write
data in SCFTDR and clear the TDFE flag to 0.

to simultaneous transmission and reception,
clear the TE and RE bits to 0, then set the both
bits to 1 simultaneously.
