Value R/W Description
5 ORER 0 R/(W)

1
Overrun Error
Indicates that an overrun error occurred during
reception, causing abnormal termination.
[Setting condition]
When the next serial reception is completed while
RDRF = 1
The receive data prior to the overrun error is
retained in RDR, and the data received
subsequently is lost. Also, subsequent serial
cannot be continued while the ORER flag is set to
1. In clocked synchronous mode, serial
transmission cannot be continued, either.
[Clearing condition]
When 0 is written to ORER after reading ORER =
1
The ORER flag is not affected and retains its
previous state when the RE bit in SCR is cleared to
0.
4 ERS 0 R/(W)
*
1
Error Signal Status
Indicates that the status of an error signal returned
from the receiving end at reception
[Setting condition]
When the low level of the error signal is sampled
[Clearing condition]
When 0 is written to ERS after reading ERS = 1
The ERS flag is not affected and retains its
previous state when the TE bit in SCR is cleared to
0.
