Section 15 Serial Communication Interface (SCI)
SCI initialization:
Set the RXD pin using the PFC.
ID reception cycle:
Set the MPIE bit in SCSCR to 1.
SCI status check, ID reception and
comparison:
Read SCSSR and check that the RDRF flag is
set to 1, then read the receive data in SCRDR
and compare it with this station’s ID.
If the data is not this station’s ID, set the MPIE
bit to 1 again, and clear the RDRF flag to 0.
If the data is this station’s ID, clear the RDRF
flag to 0.
SCI status check and data reception:
Read SCSSR and check that the RDRF flag is
set to 1, then read the data in SCRDR.
Receive error processing and break detection:
If a receive error occurs, read the ORER and
FER flags in SCSSR to identify the error.
After performing the appropriate error
processing, ensure that the ORER and FER
flags are all cleared to 0.
Reception cannot be resumed if either of
these flags is set to 1.
In the case of a framing error, a break can be
detected by reading the RXD pin value.
