2.10.9 Status Flag/Interrupt Signal
(1) Parity error
(2) Framing error
bit, the parity error flag UARTSR<PERR> is set to “1”. The UARTSR<PERR> is
cleared to “0” when the RDBUF is read after reading the UARTSR.
UARTSR<FERR> is set to “1”. The UARTSR<FERR> is cleared to “0” when the
RDBUF is read after reading the UARTSR.
When parity determined using the receive data bits differs from the received parity
When “0” is sampled as the stop bit in the receive data, framing error flag
