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.

Bit 7: Receive FIFO Overflow Interrupt Enable (RFOIE) – This bit enables an interrupt if the RFOL bit is set.
Bit 4: Receive Packet End Interrupt Enable (RPEIE) – This bit enables an interrupt if the RPEL bit is set.
Bit 3: Receive Packet Start Interrupt Enable (RPSIE) – This bit enables an interrupt if the RPSL bit is set.
Bit 2: Receive FIFO Full Interrupt Enable (RFFIE) – This bit enables an interrupt if the RFFL bit is set.
Bit 0: Receive HDLC Data Available Interrupt Enable (RHDAIE) – This bit enables an interrupt if the RHDAL bit
is set and.
