Timing diagram
Description of function
You define the length of the on and off times at the parameter T. The En input enables the
pulse generator. The pulse generator sets the output to 1 for the duration of the time T, then
to 0 for the duration of the time T and so forth, until input En = 0.
Always specify a time T of 0.1 s. A time T is not defined for T = 0.05 s and T = 0.00 s.

5.3.1.8
Asynchronous pulse generator
Description of function
The pulse shape at the output can be modified by a configurable pulse/pause ratio.
Connection
Description
Input En
You enable/disable the asynchronous pulse generator with the signal at input En.
Input Inv
The Inv input can be used to invert the output signal of the active asynchronous
pulse generator.
Parameter
T
H
, T
L
: You can customize the pulse width (T
H
) and the interpulse width (T
L
).
Output Q
Q is toggled on and off cyclically with the pulse/pause times T
H
and T
L
.
Parameters T
H
and T
L
The pulse width T
H
and the interpulse width T
L
can be provided by the actual value of
