Set the MPIE bit in SCR to 1.
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 both 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.
