Input Trg A signal at input Trg (Trigger) triggers the on-delay
timer.
Parameter T represents the time after which the output is on (0
to 1 transition of the output signal).
Retentivity:
/ = no retentivity
R = the status is retentive.
Output Q Q is on when the set time T expires, provided Trg is
still set.
Parameter T

The actual value of another already-configured functions can provide the time for parameter
T. You can use the actual values of the following functions for the value of T:
● Analog comparator (Page 188)(actual value Ax - Ay)
● Analog threshold trigger (Page 183)(actual value Ax)
● Analog amplifier (Page 195)(actual value Ax)
● Analog multiplexer (Page 213)(actual value AQ)
