detection:
If a receive error occurs, read the
ORER, PER, and FER flags in SSR to
identify the error. After performing the
appropriate error processing, ensure
that the ORER, PER, and FER flags are
all cleared to 0. Reception cannot be
resumed if any of these flags are set to
1. In the case of a framing error, a
break can be detected by reading the
value of the input port corresponding to
the RxD pin.
Read SSR and check that RDRF = 1,
then read the receive data in RDR and
clear the RDRF flag to 0. Transition of
the RDRF flag from 0 to 1 can also be
identified by an RXI interrupt.
To continue serial reception, before the
stop bit for the current frame is
received, read the RDRF flag and RDR,
and clear the RDRF flag to 0.
However, the RDRF flag is cleared
automatically when the DTC or DMAC
is initiated by an RXI interrupt and
reads data from RDR.
