Set the MPIE bit in SCR3 to 1.
Read OER and FER in SSR to check for
errors. Receive error processing is performed
in cases where a receive error occurs.
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.
When data is read from RDR, the RDRF flag
is automatically cleared to 0.
Read SSR and check that the RDRF flag is
set to 1, then read the data in RDR.
If a receive error occurs, read the OER and
FER flags in SSR to identify the error. After
performing the appropriate error processing,
ensure that the OER 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.
