Description
A positive edge ( 0 to 1 transition) at input En (Enable)
triggers the on-delay time of
the random generator.
A negative edge ( 1 to 0 transition) at input En (Enable)
triggers the off-delay time of
the random generator.
The on-delay is set at random to a value between 0s
and TH.
The off-delay is set at random to a value between 0s
and TL.
Output Q is set when the
on-delay has expired and if
En is still set. It is reset when
the off-delay has expired,
provided En was not set
again meanwhile.
Parameter TH and TL
Note the defaults of the TH and TL parameters listed in Chapter 4.3.2.
