First logic state (number 0) is the trigger output

== Trigger Word Bits ==

 . [0] - pulser 305 Hz
 . [7:1] - NIM7..NIM1 (NIM line)
 . [8] - LVDS1 (ST line)
 . [9] - LVDS6 (TQDC1 line)

== Input Counters Mapping ==
Input counter are enabled by TTC SPILL signal. The mapping between counter number, input channel and trigger logic line is following:

 . [0] - pulser
 . [1] - NIM1 (NIM line)
 . [2] - NIM2 (NIM line)
 . [3] - NIM3 (NIM line)
 . [4] - NIM4 (NIM line)
 . [5] - NIM5 (NIM line)
