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, read
RDR, and clear the RDRF flag to 0.
The RDRF flag is cleared automatically
when DTC * is activated by an RXI
interrupt and the RDR value is read.
(H8S/2268 Group only)
automatically clears the RDRF flag,
occurs only when DISEL in DTC is
0 with the transfer counter not
being 0. Therefore, the RDRF flag
should be cleared by CPU when
DISEL is 1, or when DISEL is 0
with the transfer counter being 0.
