Pinout question of STM32H723ZG board

[sidney]

Hello,

UM2407 is the user manual of the STM32H723ZG Nucleo-144 development board. Likewise, the schematics of this board are available as https://www.st.com/resource/en/schematic_pack/mb1364-h723zg-e01_schematic.pdf.

In both the manual and the schematics, there are multiple references to "PF0/PH0" and "PF1/PH1". See, for example, Section 6.5.1. This confuses me, because I don't see how the MCU pin PF0 relates to PH0 (likewise for PF1 and PH1). As far as I can tell, this peculiar labeling is not explained anywhere.

In the MCU's datasheet DS13313, there are separate pins for PH0, PF0, PH1, and PF1.

Can anyone tell me what I am missing here? Why is the labeling as it is?

Cheers, Sidney

You can ask for documentation improvement here, and maybe in 2 years it's still not done...

It would be useful to explicitly explain this dual label in UM2407 and the schematic. Is it possible to log a documentation improvement request or sometging like that?

Already opened an internal ticket 191685 to check first the situation and if there will be an issue in the documentation and second for follow-up of the fix (if there will be any ..).
