11.1. PWM

In case a GPIO shall run as PWM, the parameters "ratio" and "period" define its behavior. The
parameter "period" defines the period of the PWM signal. The parameter "ratio" defines the
ratio between on- and off-time. As an example, a ratio of 0x40 corresponds to 25% on-time
and 75% off-time.
