FLEXPWM Frequency Update, for Model Based Dev. (MPC5744P)

Hello

 

I was trying to use frequency update block  for Model  Based Dev toolbox for Mpc574x (snapshot below) for Flex PWM (model is attached)

I observed that the PWM block is not switching anymore (when I update the frequency of switching to 1000 Hz) The low side remains 0 and the high side remains high. 

So, it means the Duty Cycle remains 100 % somehow for the complementary PWM when I propose it to be 50%(see below scope).

Could you please investigate the behavior?

Or maybe I am doing something wrong
