Description
Indicates that receive data is stored in RDR.
[Setting condition]
[Clearing conditions]
The RDRF flag is not affected and retains its previous
value when the RE bit in SCR is cleared to 0.

When serial reception ends normally and receive
data is transferred from RSR to RDR
1
When an RXI interrupt request is issued allowing
DTC to read data from RDR
When RFU is activated by RDRF = 1 allowing data
to be read from RDR (only for SCI_0 and SCI_2)
When the next serial reception is completed while
RDRF = 1
When 0 is written to ORER after reading ORER =
1
When a low error signal is sampled
When 0 is written to ERS after reading ERS = 1
When a parity error is detected during reception
When 0 is written to PER after reading PER = 1
When 0 is written to RDRF after reading RDRF =
