Bit #
Name
Default
Bit 0/Send BOC (SBOC). Set = 1 to transmit the BOC code placed in bits 0 to 5 of the TFDL register.
Bits 1 to 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.
Bit 3/Receive BOC Reset (RBR). A 0 to 1 transition will reset the BOC circuitry. Must be cleared and set again for a
subsequent reset.
Bit 4/Receive BOC Enable (RBOCE). Enables the receive BOC function. The RFDL register will report the received BOC
code.
Bit 5/Unused, must be set to zero for proper operation.
Bit 6/Unused, must be set to zero for proper operation.
Bit 7/Unused, must be set to zero for proper operation.
