Bit Bit Name Initial Value R/W Description

3 PER 0 R/(W)*

Parity Error

Indicates that a parity error occurred while

receiving in asynchronous mode and the reception

has ended abnormally.

[Setting condition]

• When a parity error is detected during reception

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. In

clocked synchronous mode, serial transmission

cannot be continued, either.

[Clearing condition]

• When 0 is written to PER after reading PER = 1

• The PER flag is not affected and retains its

previous state when the RE bit in SCR is

cleared to 0.
