WebYou need to take a step back and think about how a digital PWM works. If you want to have 16 bits of resolution, typically the clock needs to run at 2^16 times the PWM output frequency. That's because the input clock to the PWM unit only increments a count by one, but you get your output frequency from the carry-out of this counter.
