21.4.2 Automatic PWM phase shift
CNT0
CNT1
Simultaneous switching of sine and cosine output could lead to a fluctuation of
the power supply and increase the susceptibility to electromagnetic
interference. To prevent this for drivers 1 to 4, the output signals are
automatically shifted by one timer count clock cycle defined in MCNTCn0.
The same accounts for the output signals of drivers 5 and 6. They are
controlled by the timer count clock defined in MCNTCn1.
Output timing of signals SM11 to SM44
Output timing of signals SM51 to SM64
