Overrun Error
Indicates that an overrun error occurred while
receiving and the reception has ended abnormally.
[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
reception 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 = 1
The ORER flag is not affected and retains its
previous state when the RE bit in SCR is
cleared to 0.
