Hi, I'm developing an application based on STM32U031K8. I need to use the IRTIM peripheral to create an IR transmitter. I set TIM15_CH1 and TIM16_CH1 as "Output Compare No Output" but IRTIM peripheral still cannot be activated. May someone help me?

    Hello @aerauliqa 

    Thank you for reporting,

    Actually, IRTIM is not supported by STM32U0 MCUs.
    It seems that CubeMX is being displayed incorrectly. I have escalated the issue to the relevant team for review and correction in internal ticket 193280.

    KR,

    Not supported? In the STM32U031 data sheet the IRTIM peripheral is mentioned. See the attached screen-shot.
