Hello,

      I want to  switch on and off the FET pre-drivers in order to reduce the current. My code is :

      if(PTT_PTT1)

         {

               PMFENCA_PWMENA = 0;

         }

          else

         {

               PMFENCA_PWMENA = 1;

          }

       if I clear the PMFENCA_PWMENA bit, the PMF can work well after set the PMFENCA_PWMENA bit.

 

I also find this in the RM,but I do not understand.

Any idea? 

 

Thanks!
