7	6	5	4	3	2	1	0
-	-	-	-	-	AEBE	AAIS	ARA
0	0	0	0	0	0	0	0

Bit 2: Automatic E-Bit Enable (AEBE)

0 = E-bits not automatically set in the transmit direction 1 = E-bits automatically set in the transmit direction

Bit 1: Automatic AIS Generation (AAIS)

0 = disabled

1 = enabled

Bit 0: Automatic Remote Alarm Generation (ARA)

0 = disabled

Bit 4: Receive BOC Enable (RBOCE). Enables the receive BOC function. The TR.RFDL register reports the received BOC code and two information bits when this bit is set.

0 = receive BOC function disabled

1 = receive BOC function enabled; the TR.RFDL register reports BOC messages and information

Bit 3: Receive BOC Reset (RBR). A 0-to-1 transition resets the BOC circuitry. Must be cleared and set again for a subsequent reset.

Bits 1 – 2: Receive BOC Filter Bits (RBF0, RBF1). The BOC filter sets the number of consecutive patterns that must be received without error prior to an indication of a valid message.

		Valid Sequence Identification
0	0	None
0	1	3
1	0	5
1	1	7

Bit 0: Send BOC (SBOC). Set = 1 to transmit the BOC code placed in bits 0 to 5 of the TR.TFDL register.
