● In this case, the following is set;
To expand “H” interval of carrier wave is invalid (V23 = “0”),
Timer 2 carrier wave generation function is valid (V22=“1”),
Count source XIN/2 selected (V21=“1”),
“L” interval (0316) of carrier wave is set to reload register R2L
“H” interval (0216) of carrier wave is set to reload register R2H
Notes 1: When the carrier wave generation function is vaild (V22=“1”), avoid a timing
when timer 2 underflows to stop timer 2. When the timer 2 count stop occurs
at the same timing with the timer 2 underflows, hazard may occur in the carrier
wave output waveform.
2: When the timer 2 is stopped during “H” output of carrier wave while the carrier
wave generation function is valid, it is stopped after the “H” interval set by
reload register R2H is output.
