Description
1
On the rising edge of input E (on-delay):
  • time-out ti is launched (time-base of 0.1ms),
  • outputs x and x Aux change to 1.
2
When time-out ti is over, outputs x and x Aux change to 0.
If a new rising edge for input E occurs before time-out ti has elapsed, outputs x and x Aux remain at 1 for a further time-out ti.
