STM32F7, H7: Where can I find info from which APB bus is a given timer clocked?

[Wowa]

Hello!

For some time already I cannot find this in manuals. Can someone point me if there is any table somewhere? Of course I can find it out experimentally, but it would be more convenient to know where it is listed.

The mapping is contained in the table Register boundary addresses, usually in section 2 of the Reference Manual. In addition to the border addresses, it also contains the responsible bus.

Good luck!

Thank you very much! For sure I wouldn't find this place myself :)).

This is what I've asked several times as a CubeMX feature: for each timer, please show where its clock comes from. Even more, show the current clock frequency from the clock config view.

You could add it as an Idea, to be ignored by ST over there.

I opened the RM but looked over it, for those not awake in the morning this visual :):

In RM0433 which I am using for the STM32H753, the timer clocking can be determined by the RCC_APB1LRSTR and RCC_APB2RSTR register definitions in Section 8.8, Table 84.
