On the FRDM-KL25Z, when I declare pins PTA5 and PTD2 as PwmOut pins, they are locked together and can not be independently controlled. It doesn't matter if I change the PWM of PTA5 or PTD2. Whichever one is changed, the other one follows it. The simple code below should keep pin PTD2 at 0% pwm while pin PTA5 should switch between 50% and 0% every 0.5 seconds. Pin PTA5 does alternate between 50% and 0% pwm, but instead of staying at 0% pwm, pin PTD2 follows pin PTA5.
