PWM wave form changed to normal on or off state.
case of single side PWM (Non complimentary PWM) , one side output PWM without dead time, and the other
side output Low level or High level by setting MDCRB<SPWMEN> and CMPU<SPWMU>,
CMPV<SPWMV>, CMPW<SPWMW>.
In case of the PWM duty close to 100% or 0% and PWM pulse width is smaller than the dead time period,
In order to avoid these PWM wave form change, single side PWM (Non complimentary PWM) is used. In
