Bit 2: Receive FIFO Full (RFF) – When 0, the Receive FIFO contains 255 or less bytes of data. When 1, the
Receive FIFO is full.
Bit 1: Receive FIFO Empty (RFE) – When 0, the Receive FIFO contains at least one byte of data. When 1, the
Receive FIFO is empty.
Bit 0: Receive HDLC Data Available (RHDA) – When 0, the Receive FIFO contains less data than the Receive
HDLC data available level (RDAL[4:0]). When 1, the Receive FIFO contains the same or more data than the
Receive HDLC data available level.

Bit 7: Receive FIFO Overflow Latched (RFOL) – This bit is set when a Receive FIFO overflow condition occurs.
An overflow condition results in a loss of data.
Bit 4: Receive Packet End Latched (RPEL) – This bit is set when an end of packet is stored in the Receive FIFO.
Bit 3: Receive Packet Start Latched (RPSL) – This bit is set when a start of packet is stored in the Receive FIFO.
Bit 2: Receive FIFO Full Latched (RFFL) – This bit is set when the RFF bit transitions from 0 to 1.
Bit 0: Receive HDLC Data Available Latched (RHDAL) – This bit is set when the RHDA bit transitions from
0 to 1.
