STM32L4P5xx and RGB222 (6 bits)

[PRV]

Please explain how the RGB 222 mode works for the STM32L4P5. Are descriptions of this mode available in application notes?

Where do you see that mode? I can't find any reference to it in RM0432.

page 17 (7. For 48-pin and 64-pin packages, only RGB222 parallel output is supported.)

and STM32CubeMX.

Okay, so that's probably just an euphemism to say that you don't have available other than the uppermost RGB pins. As there's no such mode in LTDC, in program, you use it in the same way as any other RGB mode.
