Random generator
Short description
The output of a random generator is toggled within a configurable time.
Connection
Description
Input En
The positive edge (0 to 1 transition) at the enable input En (Enable) triggers the
on-delay for the random generator.
The negative edge (1 to 0 transition) triggers the off-delay for the random
generator.
Parameter
T
H
: The on-delay is determined at random and lies between 0 s and T
H
.
T
L
: The off-delay is determined at random and lies between 0 s and T
L
.
Output Q
Q is set on expiration of the on-delay if En is still set. It is reset when the off-
delay time has expired and if En has not been set again.
Parameters T
H
and T
L
The on-delay time T
H
and the off-delay time T
L
can be provided by the actual value of
another already-programmed function:
● Analog comparator: Ax - Ay
