Bit 0/Receive BOC Detector Change-of-State Event (RBOC). Set whenever the BOC detector sees a change of
state to a valid BOC. The setting of this bit prompts the user to read the RFDL register.
Bit 1/Receive FDL Match Event (RMTCH). Set whenever the contents of the RFDL register matches RFDLM1
or RFDLM2.
Bit 2/TFDL Register Empty Event (TFDLE). Set when the transmit FDL buffer (TFDL) empties.
Bit 3/RFDL Register Full Event (RFDLF). Set when the receive FDL buffer (RFDL) fills to capacity.
Bit 4/RFDL Abort Detect Event (RFDLAD). Set when eight consecutive 1s are received on the FDL.
Bit 5/BOC Clear Event (BOCC). Set when 30 FDL bits occur without an abort sequence.
