Front Panel TRG‐OUT (GPO) Enable Mask (0x8110, R/W, C) This register sets which signal can contribute to generate the signal on the front panel TRG‐OUT LEMO connector (GPO in case of DT and NIM boards). Bit Description [7:0] Bit n corresponds to the trigger request from channel n (n=0,...,7) that partecipates to the TRG-OUT signal. [9:8] TRG-OUT (GPO) Generation Logic. The enabled trigger requests (bits [7:0] or [3:0]) can be combined to generate the TRG-OUT (GPO) signal. Options are: 00 = OR; 01 = AND; 10 = Majority; 11 = Reserved. [12:10] Majority Level. Sets the majority level for the TRG-OUT (GPO) signal generation. Allowed level values are between 0 and 7 for VME boards, while between 0 and 3 for DT, NIM and 8-channel VME boards. For a level m, the trigger fires when at least m+1 of the trigger requests are generated by the enabled couples of channels (bits [7:0] or [3:0]) . [28:13] Reserved. [29] LVDS Trigger Enable (VME boards only). If the LVDS I/Os are programmed as outputs, they can participate in the TRG-OUT (GPO) signal generation. They are in logic OR with the other enabled signals (bits[31:30] and bits[7:0], or [3:0]). Options are: 0 = disabled; 1 = enabled. [30] External Trigger. When enabled, the external trigger on TRG-IN can participate in the TRG-OUT (GPO) signal generation in logic OR with the other enabled signals (bit[31] and bits[7:0] or [3:0]). Options are: 0 = disabled; 1 = enabled. [31] Software Trigger. When enabled, the software trigger can participate in the TRG-OUT (GPO) signal generation in logic OR with the other enabled signals (bit[30], bits[7:0] or [3:0]). Options are: 0 = disabled; 1 = enabled.
