I need to control 4 motors with pwm frequency acording two analog inputs. I have a m5 core, i see it has only 2 timers available so i think I can only have two different output frequencies. Right?

How can I control four different pwm frecuency outputs? I'm not sure which could be the best option. There is some module capable of ouptut a diferent frecuency pwm output? Or maybe I can sync three ATOM PWM modules with CORE? How i can do to communicate the four modules fastly sharing the analog core input?
Any help will be welcomed.

Thanks!!
