Bit Bit Name Initial 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*
2
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 1 returned from
the reception side 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*
2
The ERS flag is not affected and retains its previous
state when the RE bit in SCR is cleared to 0.
