If the PWM is configured to run at a switching frequency of 200 kHz (switching period of 5 us), 100% duty cycle will be achieved when the duty cycle register is set to 80 clocks (80 x 62.5 ns = 5 us). This would make the effective PWM resolution only slightly more than six bits, as there are 80 steps to choose from. This
