STM32Cubemx and datasheet pin description mismatch!

[SDura.2]

Hello, I am an engineer working at Desird Arge Design. I had a problem with the STM32G031F6P6 processor. I think there is an error while selecting the timer channels in the STM32 Cubemx application. According to the datasheet description, TIM1; It includes 4 channels and 3 reverseers. When I check the list, I can confirm the information. However, when I use the STM32 Cubemx program for pin selection, the pins cannot be selected, the channel and inverting channels in the alternative pins conflict. Photos are attached. Would you help me with this topic?

Hello @SDura.2​ 

Thanks for your post,

If I well understood your question, it's related to the missed TIM1_CH3 signal on PA10 pin in CubeMX contrary to what is mentioned in the DS, right?

Actually, if it's the case, it's a normal behavior and it's not an issue.

In fact, the G031F6 is based on TSSOP20 package, and the TIM1_CH3 signal is only available for LQFP32 / UFQFPN32 and LQFP48 / UFQFPN48 packages as presented in the image below:
