Bit Bit Name Initial Value R/W Description
5 ORER 0 R/(W)*
1
Overrun Error
Indicates that an overrun error occurred while
receiving and the reception has ended abnormally.
[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
reception 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
[Setting condition]
• When the low level of the error signal is
sampled
[Clearing conditions]
• When 0 is written to ERS after reading ERS = 1
