R/W
R/(W)* Parity Error
R
R/W
Indicates that a parity error occurred while receiving in
asynchronous mode and the reception has ended
abnormally.
[Setting condition]
•
If a parity error occurs, the receive data is transferred to
RDR but the RDRF flag is not set. Also, subsequent
serial reception cannot be continued while the PER flag
is set to 1.
[Clearing condition]
•
The PER flag is not affected and retains its previous
state when the RE bit in SCR is cleared to 0.

The initial value should not be changed.
When a parity error is detected during reception
When 0 is written to PER after reading PER = 1
When the TE bit in SCR is 0
When TDRE = 1 at transmission of the last bit of a
