#There are many rogue fields, but only a handful need to be configured. what are they?
#1) the FIR coefficients. after accounting for parabolic fitting detection
#2) start and stop?
#3) main by pass. (still isn't working with FEX in hardware, but does in simulation.)
#4) all prescalers. This has potential to crash linux kernel during hi rate and low prescaling. How to add protection? Slow ramp?
#5) low pass on background
#6) op code (now called readout group). there's no rogue counter part of this yet.
#7) the load coefficients bit needs to set to one for the FIR coefficients to be written.
#8) camera rate and soft or hard trigger. The soft trigger is for offline testing. For users or just for me?
#9) the batcher bypass so soft trigger doesn't halt.
