What is the maximum frequency of the PWM using the FTM0 on a MK22FN128VLL10?


Why I ask is because I can generate a PWM of 10kHz and duty cycle of 50% using the expected numbers for the registers for FTM0.  However, when I try to generate a PWM of 20kHz and duty cycle of 50%, the duty cycle is only 40%.


The frequency is core clock is 96MHz.  Bus clock is 48MHz.
