Documentation of LCDC.2 never mentions which of the two values is for what size

[Ptival]

It'd be nice to not have to guess. The other bits' descriptions mention what 0 and 1 correspond to in general.

It is mentioned in the overview at the top of the page.

OBJ size: 0 = 8×8; 1 = 8×16

It is indeed mentioned in the main LCDC paragraph at the top, as @Peewi mentioned.

However, I noticed that for the other bits we seem to normally report what the bit switches to, often in detail (e.g. see LCDC.3) - but on LCDC.2 we're just mentioning "1 tile or 2", so maybe it makes sense to explicitly state the values there as well?
