BC: Received frame Byte Count.
The total number of valid bytes read from the RX FIFO
during the last HDLC frame.
BFRE: Buffered Framing Error.

1 - A framing error occurred during the last frame, causing
the remainder of the frame to be discarded.
BROR: Buffered Receiver Over Run.
0 - The RX buffer did not overrun during the last frame.
1 - The receive FIFO did overrun during the last frame.
The remainder of the frame was discarded.
BCRE: Buffered CRC Error.
0 - No CRC check errors occurred in the last frame.
