If startTrig or stopTrig is 2, the operation starts or stops when the incoming data matches
the pattern on all bits declared significant by lineMask. If startTrig or stopTrig is 3, the
operation starts or stops when the incoming data ceases to match the pattern on all bits
declared significant by lineMask. The lineMask also controls which bits are significant for
change detection, if used. See
DIG_Block_PG_Config for information about change
detection.
Bits that are significant for one purpose are significant for all purposes. If you configure
both change detection and a start or stop trigger, the same lineMask applies to both.
If you configure both change detection and a pattern-detection message using
Config_DAQ_Event_Message, use DAQTrigVal0 instead of lineMask to control
which bits are significant.
