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