BU21170MUV
Interrupt of PWM continuous flashing
When PWM configuration is set to not always lights, PWM drive repeat as many times as the setting value. The interrupt is
released at finishing PWM drive.
In the case that PWM always lights, the way to turn PWM off is to write â0â to the Control PWM function register which value
is â1â, and the interrupt is released at finishing PWM drive. However, if you restart the PWM timer before the PWM timer will
not finish, the interrupt is not released.
