STM32H723 - PCKL1 & PCLK2 missing from clock tree in CubeMX 6.16.1 & 6.17.0

This had me stumped for a while - Thought I was going blind for a second LOL.

PCLK1 and PCLK2 identifiers are missing from the clock tree diagram for the STM32H723.

(They are present in the trees for F103, G431, F446 and F723).

Hello @Bags 

After checking the clock tree of the STM32H723, I found PCLK1 and PCLK2.

Please try using the search bar: you should get 3 matches for PCLK2 and 4 matches for PCLK1 .The matching results will appear in green.PCLK2.png

Hi,

Your reply shows where the PCLK signals are used. It does not show where the signals come from.

For example F446 below (same goes for all the other MCUs I listed except the H723)...
