R/W
R/(W)* Overrun Error
R/(W)* Error Signal Status
Description
Indicates that an overrun error occurred during
reception, causing abnormal termination.
[Setting condition]
•
The receive data prior to the overrun error is retained
in RDR, and the data received subsequently is lost.
Also, subsequent serial reception cannot be
continued while the ORER flag is set to 1. In clocked
synchronous mode, serial transmission cannot be
continued, either.
[Clearing conditions]
•
•
The ORER flag is not affected and retains its previous
state even if the RE bit in SCR is cleared to 0.
Indicates that the status of an error signal returned
from the receive side at transmission.
[Setting condition]
•
[Clearing conditions]
•
•
The ERS flag is not affected and retains its previous
state even if the TE bit in SCR is cleared to 0.
