bit 4

RIDLE: Receiver Idle bit (read-only)

1

 = Receiver is Idle

0

 = Receiver is active

bit 3

PERR: Parity Error Status bit (read-only)

1

 = Parity error has been detected for the current character (character at the top of the receive FIFO)

0

 = Parity error has not been detected

bit 2

FERR: Framing Error Status bit (read-only)

1

 = Framing error has been detected for the current character (character at the top of the receive

FIFO)

0

 = Framing error has not been detected

bit 1

OERR: Receive Buffer Overrun Error Status bit (read/clear only)

1

 = Receive buffer has overflowed

0

 = Receive buffer has not overflowed. Clearing a previously set OERR bit (

1

→ 0

 transition) will reset

the receiver buffer and the UxRSR to the empty state.

bit 0

URXDA: Receive Buffer Data Available bit (read-only)

1

 = Receive buffer has data, at least one more character can be read

0

 = Receive buffer is empty

Value of bit only affects the transmit properties of the module when the IrDA encoder is enabled 
(IREN =

1

).
