Correct OTG_FS FIFO size for STM32H753

[DZimm.9]

Hi,

We are currently using STM32H753 and are setting up USB Fifos. There is some contradictory information about the available sizes. 
AN4879 mentions that the available SRAM size is 1.25kBytes for OTG_FS:

In the reference manual RM0433 I can only find 4kB for both OTG_HS peripherials, where OTG_HS1 is used for OTG_FS:

What information is correct?

Thanks and best regards

Daniel

Hello @DZimm.9 
Sorry for not coming back to you sooner
the OTG_FS FIFO size mentioned in the reference manual is the correct one and AN4879 will be corrected in the future
