IC20Div has no effect on clock tree

harald · ‎2025-12-15

Hy,

I try to configure MCO2 as adjustable clock out. For evaluation I use STM32N6 DK and STM32CubeMX 6.16.0 and STMCubeIDE 2.0.0

I use all different settings and it works fine, but IC20 div setting has no effect.

When I compare generated code, I see no difference, no matter what setting I put in IC20 div, neither changes the clock output frequency.

Regards

Harald
