+To enable trigger box logic which is described in this subsection (Fig.\ref{cts_logic})
+it is necessary to set register A0C5 to 40000000.

+When Trigger Logic is not used (A0C5 bit 30 = 0 ) the configuration of the used logic is simple (just accepting the input triggers see address A0C5).
+In this case when calibration trigger is set (0xA0C7;A0C5 bit 30 = 0) still the reference time/hold signal is send. When Trigger Logic is enabled and register 0xA0DC is used to overwrite trigger code. In this case if calibration trigger is send there is no reference time/hold signal. 
+It is recommended to start system ether with simple or trigger logic and do not switch between them when it is running.
