SYNC[7]
CH0
CH1
Both A and Y effectively start at the same time. A finishes earlier, then it links to B, which waits for the SYNCTRIG[7] bit to be set before
loading C. Y finishes after B is loaded, and it links to sync structure Z, which sets the SYNCTRIG[7] bit. Channel 0 responds to the
trigger set by loading C for the final data transfer.
