Section 13 Serial Communication Interface
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): Indicates that data reception ended abnormally due to a framing
error in asynchronous mode.
Notes: 1. Clearing the RE bit to 0 in SCR does not affect the FER flag, which retains its previous

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.
Description
Receiving is in progress or has ended normally
[Clearing conditions]
A receive framing error occurred *
[Setting condition]
The stop bit at the end of receive data is checked and found to be 0.
The chip is reset or enters standby mode.
Software reads ORER while it is set to 1, then writes 0.
