Read the OER flag in SSR to determine if
there is an error. If an overrun error has
occurred, execute overrun error processing.
Read SSR and check that the RDRF flag is
set to 1, then read the receive data in RDR.
When data is read from RDR, the RDRF
flag is automatically cleared to 0.
To continue serial reception, before the
MSB (bit 7) of the current frame is received,
reading the RDRF flag and reading RDR
should be finished. When data is read from
RDR, the RDRF flag is automatically
cleared to 0.
If an overrun error occurs, read the OER
flag in SSR, and after performing the
appropriate error processing, clear the OER
flag to 0. Reception cannot be resumed if
the OER flag is set to 1.
