The dead-time width can be automatically narrowed in the vicinity of 0% output or 100% output by setting the
TABnOPT2.TABnDTM bit to 1.
By setting the TABnDTM bit to 1, the dead-time counter is not cleared, but starts down counting if the TOBnm
(internal signal) output of timer AB changes during dead-time counting.
The following timing chart shows the operation of the dead-time counter when the TABnDTM bit is set to 1.

after the TABnCTL0.TABnCE 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 TABnCCRm = 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.
