429 / 750 page ![]() Section 12 Serial Communication Interface Rev.6.00 Jun. 03, 2008 Page 381 of 698 REJ09B0074-0600 Bit Bit Name Initial Value R/W Description 5 ORER 0 R/(W)* 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 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)* 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 The ERS flag is not affected and retains its previous state when the RE bit in SCR is cleared to 0. |
