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.
[Setting condition]
When one byte of the next reception is completed with
RDRF = 1
[Clearing condition]
When writing 0 after reading ORER = 1
(When the CPU is used to clear this flag by writing 0
while the corresponding interrupt is enabled, be sure to
read the flag after writing 0 to it.)
Reserved
These bits are always read as 0. The write value should
always be 0.
