Are new DMA2D modes specified correctly in the Rev.5 Reference Manual?

[Oleg Skydan]

Hi, All!

I saw the new DMA2D modes appeared in the rev.5 of the Reference Manual (see page 709, field MODE of the DMA2D->CR). They are:

100: Memory-to-memory with Blending and fixed color FG (BG fetch only with FG and

BG PFC active)

101: Memory-to-memory with Blending and fixed color BG (BG fetch only with FG and

BG PFC active)

But when I try to use them it does not seem to produce expected results. So, do those modes really work on STM32H743 ?

BTW, the 101 mode description seem to have error. It seem the correct text should be:

101: Memory-to-memory with Blending and fixed color BG (BG FG fetch only with FG and

BG PFC active)

Also the manual is not consistent if the MODE field is two bits wide (as was in older Reference Manual) or three ones.

Thanks!

Oleg
