HRTIM has minimum CR values????

[Javier1]

After a day of debugging, apparently HRTIM has minimum CR values, this means im not able to trigger any CR event close to the 0% of my scale, in my case this translates to a discontinuity in the lower end of my phase shift control.

 

Is there any way around this? reading RM0364 page 842

I tried removing the HRTIM Clock multiplication from x32 to x1 , no difference

 

Edit Maybe i need to go slower? (so this is actually a WorseResolutionTimer)

Nah, still <32 does nothing

The only "solution" i have right now is to suck it up and assume im going to have a small dimp in the otherwise linear and flat Master Timer.

Via software i will introduce a non linearity , ill make " jump the fence"  all Compare registers aimed between 0 and 32 , and use this area as least as possible.

 

This will be seen as a small jump in the modulation in the rare cases my timers have to go there.
