description: |
Sets timer counter mode.
Use constants defined in dt-bindings/timer/stm32-timer.h.
* STM32_TIM_COUNTERMODE_UP - used as upcounter.
* STM32_TIM_COUNTERMODE_DOWN - used as downcounter.
* STM32_TIM_COUNTERMODE_CENTER_DOWN - counts up and down alternatively.
Output compare interrupt flags of output channels
are set only when the counter is counting down.
* STM32_TIM_COUNTERMODE_CENTER_UP - counts up and down alternatively.
Output compare interrupt flags of output channels
are set only when the counter is counting up.
* STM32_TIM_COUNTERMODE_CENTER_UP_DOWN - counts up and down alternatively.
Output compare interrupt flags of output channels
are set only when the counter is counting up or
down.
If absent, then STM32_TIM_COUNTERMODE_UP is used (reset state).
