Usually, the TOAB1m (internal signal) output of TAB1 changes only once during dead-time counting, only in the
vicinity of 0% and 100% output. This section shows an example where the TAB1CCR0 register (carrier cycle)
and TAB1DTC register (dead-time value) are incorrectly set. If these registers are incorrectly set, the TOAB1m
(internal signal) output of TAB1 changes twice or three times during dead-time counting. The following
flowchart shows the 6-phase PWM output wave in this case.
counter
(a) When TAB1OPT2.TAB1DTM bit = 0, TAB1CCR0 register = 0006H, TAB1DTC register = 000FH,
(b) When TAB1OPT2.TAB1DTM bit = 1, TAB1CCR0 register = 0006H, TAB1DTC register = 000FH,
