Rewrite in <1> interval (rewrite during up count)
Since reload is performed at the peak interrupt timing, an asymmetric triangular waveform is
output.
Rewrite in <2> interval (rewrite during down count)
Since reload is performed at the valley interrupt timing, an asymmetric triangular waveform is
output.
