It seems clear enough that the maximum count frequency for the KV4x series directly relates to the Peripheral Bus Clock rate (for Example 100MHz). Can I really expect anything at all near 100MHz, or should I derate for some reason?
However, I wasn't able to find any relative method of estimating the maximum count frequency for a FTM based Quadrature Decoder.
I assume it has something to do with the chosen clock. but perhaps it takes several "clock cycles" to sample/debounce/filter the incoming signal. Is there a good FTM "derating" that I should apply?
