The MSCSS has 4 PWM blocks that can operate synchronously and can each produce 6 PWM outputs. The different operation modes are continuous, burst, trap, and run-once. The first 3 modes are explained in detail in the upcoming slides. It is possible to reconfigure the PWM outputs ‘on the fly’ by enabling new sets of parameter values. A mechanism is provided to allow an atomic change of the PWM configuration without disturbing the currently generated PWM outputs. Therefore two sets are available for each register. The software uses one set while the other set, the shadow register, is used by the PWM. Capture functionality is also provided.
