C, W, ML, MR, BL and BR above refer to layers of previous products. Window mode or compatibility
mode can be selected for each layer. It is possible to use new functions via minor program changes by
allowing the coexistence of display modes instead of separating them completely.
However, if high resolutions are displayed, the simultaneously-displayed layer count and pixel data
may be restricted according to the graphics memory's ability to supply data.
