Bit 3: Receive FEAC FIFO Empty (RFFE) – When 0, the Receive FIFO contains at least one code. When 1, the
Receive FIFO is empty.
Bit 1: Receive FEAC Codeword Detect (RFCD) – When 0, the Receive FEAC Processor is not currently receiving
a FEAC codeword. When 1, the Receive FEAC Processor is currently receiving a FEAC codeword.
Bit 0: Receive FEAC Idle (RFI) – When 0, the Receive FEAC processor is not receiving a FEAC Idle signal (all
ones). When 1, the Receive FEAC processor is receiving a FEAC Idle signal.

Bit 2: Receive FEAC FIFO Overflow Latched (RFFOL) – This bit is set when a Receive FIFO overflow condition
occurs. An overflow condition results in a loss of data.
Bit 1: Receive FEAC Codeword Detect Latched (RFCDL) – This bit is set when the RFCD bit transitions from 0
to 1.
Bit 0: Receive FEAC Idle Latched (RFIL) – This bit is set when the RFI bit transitions from 0 to 1. Note:
Immediately after a reset, this bit will be set to one.
