The dead-time width can be automatically narrowed in the vicinity of 0% output or 100% output by setting the
TAB1OPT2.TAB1DTM bit to 1.
By setting the TAB1DTM bit to 1, the dead-time counter is not cleared, but starts down counting if the TOAB1m
(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 TAB1DTM bit is set to 1.

counter
after the TAB1CTL0.TAB1CE bit has been set. The first wave is shorter than the second wave because
the dead time is fully counted.
