Bit 5—Overrun Error (ORER): Indicates that data reception ended abnormally due to an
overrun error.

Notes: *1 Clearing the RE bit to 0 in SCR does not affect the ORER flag, which retains its
Bit 4—Framing Error (FER)/Error Signal Status (ERS): The function of this bit differs for the
normal serial communication interface and for the smart card interface. Its function is switched
with the SMIF bit in SCMR.
For serial communication interface (SMIF bit in SCMR cleared to 0): Indicates that data
reception ended abnormally due to a framing error in asynchronous mode.

but does not set the RDRF flag. Serial receiving cannot continue while the FER flag is
set to 1. In synchronous mode, serial transmitting is also disabled.
Description
Receiving is in progress or has ended normally*
[Clearing conditions]
The chip is reset or enters standby mode
Read ORER when ORER = 1, then write 0 in ORER
A receive overrun error occurred*
[Setting condition]
Reception of the next serial data ends when RDRF = 1
Description
Receiving is in progress or has ended normally*
[Clearing conditions]
The chip is reset or enters standby mode
Read FER when FER = 1, then write 0 in FER
A receive framing error occurred*
[Setting condition]
The stop bit at the end of the receive data is checked and found to be 0
