Description

ORER

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 =

The ORER flag is not affected and retains its

previous state when the RE bit in SCR is cleared to

4ERS

R/(W)*

Error Signal Status

Indicates that the status of an error signal returned

from the receiving end 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 TE bit in SCR is cleared to
