Does cubeMX have the correct AXI / AHB limits for STM32H750?

Hi,

Looking at the block diagram in the datasheet, ABH1, AHB2, AHB3, AHB4, AXI are listed as supporting 200MHz.

Cube (v5.0.0, H7 v1.3.0) however will not allow them to be set higher than 100 MHz, and says the must be <- 100MHz in the hover text.

Is cube or the datasheet correct?

Thanks,

Jacob

Nevermind, didn't realize they need to be 1/2 the core speed. It lets me do 200MHz if the core is 400 MHz.

Everything is fine : )
