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
Bit 2—Transmit End (TEND): Indicates that there is no valid data in TDR when the last bit of
the transmit character is sent, and transmission has been ended.
The TEND flag is read-only and cannot be modified.

not match the parity setting (even or odd) specified by the O/
