3. Serial reception continuation
break detection: If a receive
error occurs, read the ORER,
PER, and FER flags in
SCSSR1 to identify the error.
After performing the
appropriate error handling,
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 RxD pin.
data read : Read SCSSR1 and
check that RDRF = 1, then read
the receive data in SCRDR1
and clear the RDRF flag to 0.
procedure: To continue serial
reception, complete zero-
clearing of the RDRF flag
before the stop bit for the
current frame is received. (The
RDRF flag is cleared
automatically when the direct
memory access controller
(DMAC) is activated by an RXI
interrupt and the SCRDR1
value is read.)
