Hi Oliver >From what I can see, that port determines how quickly the phase offset applied to all channels is incremented. So your value tells it to increment the phase offset every 4095 cycles. I am not sure if there is some way to turn off fringe-stopping.
There is some good documentation at https://casper.berkeley.edu/wiki/Finedelay_fstop_prog which may help.
