Usually, the TOQ1m (internal signal) output of TMQ1 changes only once during dead-time counting, only in the
vicinity of 0% and 100% output. This section shows an example where the TQ1CCR0 register (carrier cycle)
and TQ1DTC register (dead-time value) are incorrectly set. If these registers are incorrectly set, the TOQ1m
(internal signal) output of TMQ1 changes more than once during dead-time counting. The following flowchart
shows the 6-phase PWM output wave in this case.
