The dead-time width can be automatically narrowed in the vicinity of 0% output or 100% output by setting the
TQ1OPT2.TQ1DTM bit to 1.
By setting the TQ1DTM bit to 1, the dead-time counter is not cleared, but starts counting down if the TOQ1m
(internal signal) output of timer Q changes during dead-time counting.
The following timing chart shows the operation of the dead-time counter when the TQ1DTM bit is set to 1.

after the TQ1CTL0.TQ1CE bit has been set. The first wave is shorter than the second wave because
the dead time is fully counted.

Negative-phase wave output width: (M + 1
(e.g., output width is 4 where TQ1CCRm = M).
Dead-time counter m starts counting down.
Positive-phase wave output width: (M + 1
(e.g., output width is M
Dead-time counter m starts counting down.
