    The edge is synchronized at the next cptr edge. After all the device cptrs are aligned, an edge sent out on the fpga i/o lines is read at the same clock cycle across all the devices. Note the quality of synchronization is only as good as the quality of sample clock locking. Some static skew may exis...
