Trailing Edge
Used to ignore accidental triggers when Trigger Mode is set to External Edge or External Level.
To consider a change in state on the trigger input, the level must be stable for the trigger filter duration. In an edge mode, the scanner will trigger a read cycle if the active state has been uninterrupted for the entire trigger filter duration. In a level mode, the trailing edge is filtered such that on the falling edge, the state must be held for the trigger filter duration before the trigger will be deemed inactive.
