In Figure 42 the CID field is 0. As this field is decremented (in LSB to MSB order) the value decrements for each
SDI down the line. The BRDCST, R/W, and REG/RAM bits remain unchanged as the control word passes through
the entire chain. The odd SDIs are internal to the device and represent the SDI to SDI_THRU connection between
channels of the same device. A unique CID is presented to each channel, and the channel receiving a CID value of
zero is the target of the operation (channel 0 in this case). The last line of Figure 42 illustrates that in Broadcast
mode, all bits pass through the chain without permutation.
