bit 5

ADDEN: Address Character Detect bit (bit 8 of received data = 1)
1 = Address Detect mode enabled. If 9-bit mode is not selected, this does not take effect
0 = Address Detect mode 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/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

Note 1: Refer to Section 17. “UART” (DS70188) in the “dsPIC33F/PIC24H Family Reference Manual” for 

information on enabling the UART module for transmit operation.
