(3) Output wave in vicinity of 0% and 100% output
<1> The valley interrupt selects 100% ←→ 0% or 0% ←→ 100% output.
<2> The crest interrupt selects 100% ←→ 0% output.
If an interrupt is generated because the value of the 16-bit counter matches the value of the compare register
while dead time is being counted, the dead-time counter is cleared and starts its count operation again.
The output waveform of dead-time control in the vicinity of 0% and 100% output is shown below.
Figure 10-11. PWM Output Waveform from 0% to 100% and from 100% to 0% (With Dead Time)
Output can be selected from 100% ←→ 0% or 0% ←→ 100% immediately after the timer has been
started.
The crest interrupt selects 100% → 0% output by using the timer output forced raising function and by a
match between the 16-bit counter value and the TABnCCR0 register value.
