bit 5

 Address Character Detect bit (bit 8 of received data = 1)

1

 = Address Detect mode is enabled. If 9-bit mode is not selected, this does not take effect.

0

 = Address Detect mode is disabled

bit 4

 Receiver Idle bit (read-only)

1

 = Receiver is Idle

0

 = Receiver is active

bit 3

 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

 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

 Receive Buffer Overrun Error Status bit (clear/read-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 RSR to the empty state)

bit 0

 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
