The prescalers are currently hardcoded and are not user-selectable. As a result, the frequency of the timer can be inadequate to the task. For instance, the frequency of the 16-bit timers (prescaler 10000) is usually too low to correctly generate of PWM of a few kilohertz. Hardcoded prescalers are replaced by Kconfigs so the user can choose at compile time. The default value of each Kconfig matches the hardcoded prescaler, so the change will be transparent.
