Bit 7: Receive BOC Reset (RBR). The host should set this bit to force a reset of the BOC circuitry. Note that this is
an acknowledged reset, that is, the host need only set the bit and the DS26528 will clear it once the reset operation
is complete (less than 250μs). Modifications to the RBF[1:0] and RBD[1:0] bits will not be applied to the BOC
controller until a BOC reset has been completed.
Note: This bit will clear automatically if RMMR.INIT_DONE has been set.
Bits 5 and 4: Receive BOC Disintegration Bits (RBD[1:0]). The BOC disintegration filter sets the number of
message bits that must be received without a valid BOC to set the BC bit indicating that a valid BOC is no longer
being received.
Bits 2 and 1: Receive BOC Filter Bits (RBF[1:0]). The BOC filter sets the number of consecutive patterns that
must be received without error prior to an indication of a valid message.
Note 1: The DS26528’s BOC controller does not integrate and disintegrate concurrently. Therefore, if the maximum integration
time and the maximum disintegration time are used together, BOC messages that repeat fewer than 11 times may not be
detected.

Bits 7 to 0: Per-Channel Idle Code Bits (C[7:0]). C0 is the LSB of the code (this bit is transmitted last). Address
020h is for channel 1. Address 037h is for channel 24. Address 03Fh is for channel 32. RIDR1:RIDR24 are T1
mode only. RIDR25:RIDR32 are E1 mode only.
