MTRCKTSPS5744P - Issue for triggering PWM after Motor Driver Initialization

I am using Simulink and I could perform the Motor Driver Initialization properly.

However I faced a strange behavior after the initialization, sending the PWM signals output:


I can not update the PWM output when the PWM ports are externally triggered, as shown below:


However I can update my PWM outputs when the ports are inside the Initialization block, as can be seen below:

What is the cause of this issue?

How to make the PWM port execute externally by the trigger?


Also I am sending the models attached to make the situation easier for understanding.


Kind Regards, Rafael
