- channel of the timer used for PWM
- period to set in ns
- flags : combination of standard flags like PWM_POLARITY_NORMAL
or specific flags like STM32_PWM_COMPLEMENTARY. As an example for channel2:
<&pwm1 2 100 (PWM_POLARITY_NORMAL | STM32_PWM_COMPLEMENTARY)>;
or specific flags like STM32_PWM_COMPLEMENTARY. As an example,
the following complementary PWMs(CH2&CH2N) are shown below.
