STM32F303 OCREFCLR with Comparator Output

Hello Everyone,

I have a question about STM32F303VCT6 MCU's Hardware Comparator Unit.

I want to use 6 of the comparators as window comparator. I have no problem with this installation. But I also want to use this 3 groups of window comparators as cycle-by-cycle current limiter. So, I think I need to connect all the comparators Internal Outputs to my Timer's (TIM1 with 6 channel complementary output) OCREFCLR input. But I can't. Because, hardware just allows to set COMP1-2-3's outputs to set as 'Timer 1 Output Compare Referance Clear'. I don't have

'Timer 1 Output Compare Referance Clear'

selection with COMP4-5-6.

I need any suggestions. Please help me

Thanks a lot.

Cemre.
