The STA369BWS 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 define the maximum extension for PWM rise and fall edge, that is,

rising edge as far as the falling edge cannot range outside PWM slot boundaries.
