Description

PER

R/(W)* Parity Error

Indicates that a parity error has occurred during reception

in asynchronous mode and the reception ends

abnormally.

[Setting condition]

• When a parity error is detected during reception

Receive data when the parity error occurs is

transferred to RDR, however, the RDRF flag is not

set. Note that when the PER flag is being set to 1, the

subsequent serial reception cannot be performed. In

clocked synchronous mode, serial transmission also

cannot continue.

[Clearing condition]

• When 0 is written to PER after reading PER = 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.)

Even when the RE bit in SCR is cleared, the PER flag

is not affected and retains its previous value.
