eMIOS PWM output disable（OPWMB MODE）

FRIDAY618 — Fri, 18 Oct 2024 06:21:09 GMT

hello experts:

when (OPWMB mode)PWM dutycylce is 100%, it can not be output disabled by ODIS register.

But if the dutycycle <100%,the (OPWMB mode) PWM can be disabled output by ODIS register.Such as the dutycle is 99% the PWM(OPWMB mode) can be disable by ODIS register.

And if the PWM mode is OPWFMB,it can be disbled by ODIS when it's dutycle is 100%.

why?And have any method to solve？

I used the demo but not solved problem？

I toggled gpio_34 pin and connect gpio_34 with PTB4(TRGMUX_in,1).when the pwm dutycle is 50%.it can be disabled by ODIS.

when the pwm dutycle is 100%.it still can not be disable.
