[4] SCI status check and receive data
[5] Serial reception continuation
The RxD pin is automatically
designated as the receive data input
pin.
If a receive error occurs, read the
ORER flag in SSR, and after
performing the appropriate error
processing, clear the ORER flag to 0.
Transfer cannot be resumed if the
ORER flag is set to 1.
read:
Read SSR and check that the RDRF
flag is set to 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.
procedure:
To continue serial reception, before
the final bit of the current frame is
received, reading the RDRF flag,
reading RDR, and clearing the RDRF
flag to 0 should be finished. The
RDRF flag is cleared automatically
when the DMAC *
activated by a receive data full
interrupt (RXI) request and the RDR
value is read.
2. The case, in which the DTC
Group.
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.
