Overrun Error
Indicates that an overrun error occurred during reception,
causing abnormal termination.
[Setting condition]
•
[Clearing condition]
•
Error Signal Status
Indicates that the status of an error, signal 1 returned from
the reception side at reception
[Setting condition]
•
[Clearing condition]
•
Description
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.
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.
When the low level of the error signal is sampled
When 0 is written to ERS after reading ERS = 1*
The ERS flag is not affected and retains its previous
state when the RE bit in SCR is cleared to 0.
