Note: When to expand “H” interval of the carrier wave is valid, set “0116” or more to reload register R2H.
● In this case, the following is set;
Timer 2 carrier wave generation function is valid (V22=“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
