R Reserved
This bit is always read as 0. The write value should
always be 0.
6 ORER
0 R/W Overrun
Error
If the next data is received while RDRF
=
1, an overrun
error occurs, indicating abnormal termination. SSRDR
stores 1-frame receive data before an overrun error
occurs and loses data to be received later. While ORER
=
1, consecutive serial reception cannot be continued.
Serial transmission cannot be continued, either.
[Setting condition]
•
When one byte of the next reception is completed
with RDRF
=
1
[Clearing condition]
•
When writing 0 after reading ORER
=
1
