In Figure 28, the CID field is 0. As this field is
decremented
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.
