10.9 Status Flag
10.9.1 Parity Error
10.9.2 Framing Error
10.9.3 Overrun Error
RXD pin
UARTSR<FERR>
INTRXD interrupt
UARTSR<PERR> is set to “1”. The UARTSR<PERR> is cleared to “0” when the RDBUF is read after read-
ing the UARTSR.
The UARTSR<FERR> is cleared to “0” when the RDBUF is read after reading the UARTSR.
Shift register
UARTSR<OERR> is set to “1”. In this case, the receive data is discarded; data in RDBUF are not affected.
The UARTSR<OERR> is cleared to “0” when the RDBUF is read after reading the UARTSR.
Shift register
RXD pin
UARTSR<PERR>
INTRXD interrupt
When parity determined using the receive data bits differs from the received parity bit, the parity error flag
When “0” is sampled as the stop bit in the receive data, framing error flag UARTSR<FERR> is set to “1”.
When all bits in the next data are received while unread data are still in RDBUF, overrun error flag
