Fig. 5.6.2 Initial setting example for registers relevant to PWM mode (1)
5.6.1 Setting for PWM mode
Figures 5.6.2 and 5.6.3 show an initial setting example for registers relevant to the PWM mode.
Note that when using interrupts, set up to enable the interrupts. For details, refer to “Chapter 4. INTERRUPTS.”
Note: When operating as 8-bit pulse width modulator
