Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Indicates that an overrun error occurred during
reception, causing abnormal termination.
0: Reception in progress, or reception has ended
[Clearing conditions]
•
•
The ORER flag is not affected and retains its previous
state when the RE bit in SCSCR is cleared to 0.
1: An overrun error occurred during reception
[Setting condition]
•
The receive data prior to the overrun error is retained in
SCFRDR, and the data received subsequently is lost.
Serial reception cannot be continued while the ORER
flag is set to 1.
