PWM shift feature
In new phase shift modulation it is possible to shift one output with respect to the other one.
This can reduce the noise generated by the simultaneous switching of two or more outputs.
The shift is performed through by programming bits PS_nA and PS_nB in registers
PWMOnCFG1-2 (where n is the number, 1 to 4, of the output) beginning on page 91.
