STM32H757 Datasheet missing information

[rwareinc]

Specifically, I require a timer for creating a clock to a peripheral.  I chose PH5 (Timer12 Channel 2) because of the allocation capability in CubeMX, however, the datasheet for the STM32H757 does not show that as an alternate function.

I have confirmed that both the CubeMX software and datasheets are the latest versions...

My question is, which resource is correct and if the Alternate function is available for PH9, which AF code do I use?  It is not listed anywhere.

Hello,

Need to check internally and get back to you as soon as I have an answer.

Thank you

Documentation for PB14, PB15, PH6 and PH9 is also lacking, no TIM12 AF table entries.

AF2 per H743/H753, H72x/H73x and H7Ax/H7Bx implementations.

Nowhere do I see PH5 described, my gut is to go with the data sheets over CubeMX tables.

 

PB14:AF2 TIM12_CH1

PB15:AF2 TIM12_CH2

PH6:AF2 TIM12_CH1

PH9:AF2 TIM12_CH2

Do you mean in the Tables "XXX alternate functions" ?

Hello again,

Checking the behavior from my side I didn't reproducer it with CubeMx 6.11.1:

This is the list of option CubeMx is giving for PH5:

Could you please tell which exact STM32H7 part number you are using as I could reproduce the same config as yours?

Is there a pane / pin highlighter / picker that gets you TIM12 associativity from the other direction?

Based on interactions, STM32H757XIH6  240+25-TFBGA (14x14) 265-TFBGA

When I make a search with TIM12 wording in the pinout menu I get only Four GPIOs options PB14/PB15/PH6/PH9 which is inline with the datasheet.

No PH5 is highlighted:

@Tesla DeLorean: reported internal ticket 184676 regarding the miss of TIM12 AFs in the "alternate functions tables"

In H745 ds it is on PH9 :

Hello,

Issues fixed in an internal version of the datasheet.

It will be available soon on the ST website.
