<1> 100% output is selected by the valley interrupt (with a match with the 16-bit counter).
<2> 100% output is canceled by the valley interrupt (without a match with the 16-bit counter).
<3> 100% output is selected by the crest interrupt (without a match with the 16-bit counter).
<4> 100% output is canceled by the crest interrupt (without a match with the 16-bit counter).
Remark
The valley interrupt forcibly lowers the timer output, but raising the timer output takes precedence when
the value of the TABnCCRm register matches the value of the 16-bit counter. As a result, the 100% output
is produced.
The valley interrupt forcibly lowers the timer output. This cancels the 100% output.
The crest interrupt forcibly raises the timer output. This produces the 100% output.
The crest interrupt forcibly raises the timer output. This cancels the 100% output.
