Register addresses from 0xA000 to 0xA0ef is SCM FPGA (1)
Register addresses from 0xA0f0 to 0xA0ff is ECP2M FPGA (2)
-Register addresses from 0xA100 to 0xA100 + 10*500 which is number of samples per beam structure, the histograms are created in the SCM FPGA (1) see fig. \ref{ctsbeam}
+Register addresses from 0xA100 to 0xA100 + 26*500 which is number of samples per beam structure, the histograms are created in the SCM FPGA (1) see fig. \ref{ctsbeam}. First 8 is START next 8 is also START but perpendicularstripes. Next 8 is Veto and for the last two the source is selected by 0xA0C2 register.
