STM32H745: DS and RM disagree, which to believe?

STM32H745 datasheet says:

RTC_OUT can come out PB2 port. No other port is listed in the DS for RTC_OUT. See table 8, page 62. RTC_OUT also listed in table 10, page 90, and note for PC13, page 92.

STM32H745 reference manual says:

RTC_OUT can be directed to PC13 or PB2, with PB2 not being useful in standby/VBAT modes. See table 387, page 2081.

Okay, so which document is correct?

My instincts say the RM likely is correct, but building PCBs based on instinct will end up costing you someday, so I want the documents to be clear and consistent.

Hello,

The reference manual is the right one.

Also RM0399 is missing page 583, which makes PDF page numbers wrong after that page.

Now 2024, DS for the STM32H745XIH6 is the same...
