7.4.1.4 Double Switching PWMs
Double switching PWM output is supported to aid in single shunt current measurement
and three phase reconstruction. This method support two independent rising edges and
two independent falling edges per PWM cycle. The VAL2 and VAL3 registers are used
to generate the even channel (labelled as PWMA in the figure) while VAL4 and VAL5
are used to generate the odd channel. The two channels are combined using XOR logic
(force out logic) as the following figure shows. The DBLPWM signal can be run through
the deadtime insertion logic.
