Figure 4-2-6 External Line Trigger Input Mask Effect
①
NED_LineMaskTimeR: The time during which changes in the signal rising edge are invalid
②
NED_LineMaskTimeF:The time during which changes in the signal falling edged are invalid
Using this function you can control the generation of unwanted frames due to unexpected
variations in the signal.
③
If you set NED_LineMaskTimeR to too large a value, valid trigger changes may go undetected
and frames will not be generated, so set the value as small as possible.
④
If you set NED_LineMaskTimeF to too large a value, valid trigger changes may go undetected
and unwanted frames will be generated, so set the value as small as possible.
