51  * Each register hold 16 2-bit fields encoding the sink
52  * {0,1,2,3}, "0" means unconnected.
53  *
54  * The single FSYNCH register uses four 3-bit fields of 1-hot
55  * encoded sink information, "0" means unconnected.
56  *
57  * The encoding is redundant. The FSYNCH setting will connect
58  * a channel to a sink. At that point the LUT's belonging to
59  * that channel can be directed to another sink. Thus the data
60  * goes to another place than the synch
