comparison:
Read SSR and check that the RDRF
flag is set to 1, then read the receive
data in RDR 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.
Read SSR and check that the RDRF
flag is set to 1, then read the data in
RDR.
detection:
If a receive error occurs, read the
ORER and FER flags in SSR 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.
