14-bit resolution PWM mode: the additional pulse Ts (1) and Ts (63)
12-bit resolution PWM mode: the additional pulse Ts (1) and Ts (15)

Note 1: If the pulse width is set to “00H”, PWM will not operate. Its output will remain high.
Note 2: If the pulse width is set to “FFH”, settings for additional pulses cannot be made. Be sure to set the pulse
