(4) Automatic dead-time width narrowing function (TAB1OPT2.TAB1DTM bit = 1)

(internal signal)
Note The output width of the first wave differs from that of the second and subsequent waves immediately
Remark
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.

the dead time is fully counted.
