The rising edge of a pulse at input I sets output Q = 1 after
pulse delay time T.
When I = 0, then the function block sets Q = 0.

When I = 1, then the function block sets Q = 1.
The falling edge of a pulse at input I sets output Q = 0 after
OFF delay time T.
When input I returns to 1 before time T has expired, output
Q remains 1.
