In Figure 28, the CID field is 0. As this field is decremented (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
0 is the target of the operation (channel 0 in this case). The last line of Figure 28 illustrates that in broadcast mode,
all bits are passed through the chain without permutation.
