There are several individual timer-specific functions that can be used to change PWM output:
* :cpp:func:`ledc_timer_set`
* :cpp:func:`ledc_timer_rst`
* :cpp:func:`ledc_timer_pause`
* :cpp:func:`ledc_timer_resume`
The first two functions are called "behind the scenes" by :cpp:func:`ledc_channel_config` to provide a startup of a timer after it is configured.
