Section 15 Serial Communication Interface (SCI, IrDA)
Bit 5—Overrun Error (ORER): Indicates that an overrun error occurred during reception,
causing abnormal termination.

Notes: 1. The ORER flag is not affected and retains its previous state when the RE bit in SCR is
Bit 4—Framing Error (FER): Indicates that a framing error occurred during reception in
asynchronous mode, causing abnormal termination.

RDRF flag is not set. Also, subsequent serial reception cannot be continued while the
FER flag is set to 1. In synchronous mode, serial transmission cannot be continued,
either.
Description
[Clearing condition]
When 0 is written in ORER after reading ORER = 1
[Setting condition]
When the next serial reception is completed while RDRF = 1 *
Description
[Clearing condition]
When 0 is written in FER after reading FER = 1
[Setting condition]
When the SCI checks the stop bit at the end of the receive data when reception ends,
and the stop bit is 0 *
