    Hi,

    You can configure the mode PWM mode1 or PWM mode2 in the TIMx_CCMR1 register and then select the polarity (CC1P bit) in the TIMx_CCER1 Capture/compare enable register 1.

    regards

    Hi,

    I'm using the Timer 3 in output compare mode with toggles, each time the

    interrupt occurred, I have to change the next match value (TIMx->CCRn).

    My question is: is it possible to set the initial state in a known level?

    I'vd try to use GPIOx->ODR, but this seems not work.
