Example 13 - Output delay circuit
The output delay circuit is composed of two timers executing delay actions. No matter input X0 is
ON or OFF, output Y4 will be delayed.

The counting range of a 16-bit counter is 0 ~
32,767. The opposite circuit uses two counters to
increase the counting range as n1*n2. When
value in counter C6 reaches n2, The pulses
counted from X13 will be n1*n2.
