The STA381BWS can be configured to support different output configurations. For each
PWM output channel a PWM slot is defined. A PWM slot is always 1 / (8 * fs) seconds
length. The PWM slot defines the maximum extension for the PWM rising and falling edge,
that is, the rising edge as well as the falling edge cannot range outside the PWM slot
boundaries.
