Description
Indicates whether TDR contains transmit data.

•
Receive Data Register Full
Indicates that receive data is stored in RDR.

•
The RDRF flag is not affected and retains its
previous value when the RE bit in SCR is cleared
to 0.
Overrun Error
[Setting condition]
When the next serial reception is completed while
RDRF = 1
[Clearing condition]
When 0 is written to ORER after reading ORER = 1
Error Signal Status
[Setting condition]
When a low error signal is sampled
[Clearing condition]
When 0 is written to ERS after reading ERS = 1
When the TE bit in SCR is 0
When data is transferred from TDR to TSR, and
TDR can be written to.
When 0 is written to TDRE after reading TDRE =
1
When a TXI interrupt request is issued allowing
DTC to write data to TDR
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 0 is written to RDRF after reading RDRF
