Bit 4—Framing Error (FER): Indicates that a framing error occurred during reception in
asynchronous mode, causing abnormal termination.
Notes: 1. The FER flag is not affected and retains its previous state when the RE bit in SCR is
Bit 3—Parity Error (PER): Indicates that a parity error occurred during reception using parity
addition in asynchronous mode, causing abnormal termination.
Notes: 1. The PER flag is not affected and retains its previous state when the RE bit in SCR is

Description
[Clearing condition]
When 0 is written in FER after reading FER = 1
[Setting condition]
When the SCI checks the stop bit at the end of the receive data when reception ends,
and the stop bit is 0 *
Description
[Clearing condition]
When 0 is written in PER after reading PER = 1
[Setting condition]
When, in reception, the number of 1 bits in the receive data plus the parity bit does not
match the parity setting (even or odd) specified by the O/E bit in SMR *
