Both in the manual and in CubeMX, it is shown that my microcontroller, has the ability to configure the FMC, for an asynchronous muxed PSRAM interface.
However, in the manual I can only find the timing description for the asynchronous NOR Flash and for synchronous NOR/PSRAM.
Am I missing something here, or is it missing in the manual itself?

Hello @Giorgi_Kvernadze and welcome to the Community,
The Asynchronous multiplexed PSRAM/NOR timings tables are described in the STM32H5 datasheets.
You can check the timings Table of Asynchronous multiplexed PSRAM/NOR, in the STM32H562xx and STM32H563x datasheet

welcome to the forum
Please see How to write your question to maximize your chances to find a solution for best results.
In particular, you didn't say which microcontroller, exactly, is "your microcontroller" - thus which particular Reference Manual you are referring to.

I had something like this more in mind.

Hi @Giorgi_Kvernadze ,
Your request has been escalated through internal ticket number: 223546 to update the reference manual in the coming release.
Thank you for your contribution.
(PS: Ticket number: 223546 is only for reference and not available outside of ST).

Nice, good to hear.
Around when should the update be expected to be released?
