How to report an error of the reference manual of STM32F4xx ?

[StudentWei]

I find an error in the RM0090(STM32F4 Reference manual) as follows:

But I don't know how to report it. Please help me.

Maybe this isnt error. PDR is activated on botom value PDR and hold to hysteresis top value PDR. Any value more as top PDR start POR ...

When we speak about reference F4 i have more complicated question , MCU with DSI have LTDC setup polarity for sync and DE. I setup here AL = active LOW.

But my DSI display work ok only when in DSI config i set

VidCfg.VSPolarity = DSI_VSYNC_ACTIVE_HIGH;

???
