Usage:
Used to ignore spurious triggers when
Trigger Mode
is set to External
Edge or External Level.
Definition:
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 reader will trigger a read
cycle if the active state has been uninterrupted for the entire trigger filter
duration. In a level mode, the leading edge is filtered such that on an active
edge, the state must be held interrupted for the trigger filter duration before
a trigger will occur.
