The block supplies an impulse to the output
Out
when a positive change in edge occurs
on the input
Trig
. The length of the pulse is specified in µs on input
T
. When change in
edge is given on
Trig
before the pulse is finished, the pulse length starts again. When
signal 1 is written to the input
Reset
, the output
Out
is set to signal 0.
The output
Counter
specifies the remaining time (in µs) during which the pulse will still
be queued. When
Reset
has signal 1,
Counter
has the value 2147483647.
The output
TrigOld
shows the status of the input
Trig
