bit 5

ADDEN: 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

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-only/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: UARTx 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

Refer to “UART” (DS70188) in the “dsPIC33/PIC24 Family Reference Manual” for information on enabling 
the UART module for transmit operation.
