7.2 Display Function
7.2.1 Layer configuration
Six-layer window display is performed. Layer overlay sequence can be set in any order. A four-layer
display mode and left/right split display mode are also provided, supporting backward compatibility
with previous products.

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