parameter mode. For information about how to modify,
please refer to chapter 5.2.2.
Timing diagram
You can set the pulse/pause ratio at the T
H
(Time High)
and T
L
(Time Low) parameters.
The INV input can be used to invert the output signal. The
input block INV only inverts the output signal if the block
is enabled via EN.
If retentivity is not set, output Q and the expired time are
reset after a power failure.
Random Generator
Description of function
The output of a random generator is toggled within a
configurable time.
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.
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
.
Q is set on, expiration of the on
delay if En is still set. It is reset
when the off-delay timer has
expired and if En has not been set
again.
