Section 12 Serial Communication Interface
Bit 5—Overrun Error (ORER): Indicates that data reception ended abnormally due to an
overrun error.
Bit 5

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.

2. RDR continues to hold the receive data prior to the overrun error, so subsequent
previous value.
receive data is lost. Serial receiving cannot continue while the ORER flag is set to 1. In
synchronous mode, serial transmitting is also disabled.
Description
Receiving is in progress or has ended normally *
[Clearing conditions]
A receive overrun error occurred *
[Setting condition]
Reception of the next serial data ends when RDRF = 1
The chip is reset or enters standby mode
Read ORER when ORER = 1, then write 0 in ORER
