Description
Reserved
This bit is always read as 0. The write value should
always be 0.
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.
