Care must be exercised when using this module in the modes listed in
in their inactive states in stop mode, and optionally under WAIT and freeze modes. PWM outputs will be
reactivated (assuming they were active to begin with) when these modes are exited.

It is possible to have both channels of a complementary pair to be high. For
example, if the TOPNEGA (negative polarity for PWM0), BOTNEGA
(negative polarity for PWM1), MASK0, and MASK1 bits are set, both the
PWM complementary outputs of generator A will be high. See
