18.3 Functional Overview

Video data output

Dual digital video outputs are provided.

Screen resolution

LCD panels with wide range of resolutions are supported by using a programmable timing

generator as follows:

Hardware cursor

MB86R02 'Jade-D' supports two hardware cursor functions. Each of these hardware cursors is

specified as a 64 × 64-pixel area. Each pixel of these hardware cursors is 8 bits and uses the same

look-up table as indirect color mode.

Double buffer method

Double buffer method in which drawing window and display window is switched in units of 1 frame

enables the smooth animation.

Flipping (switching of display window area) is performed in synchronization with the vertical

blanking period using program.

Scroll method

Independent setting of drawing and display windows and their starting positions makes smooth

scrolling possible.

Display colors

• Supports indirect color mode which uses the look-up table (color palette) in 8 bits/pixels.

• An entry in the look-up table (color palette) has 8 bits, in other words 256 entries are possible. The

color data itself is saved as 6 bits of RGB data. Consequently, 256 colors can be displayed out of

260,000 possible colors.

• Supports direct color mode which specifies RGB with 16 bits/pixel.

• Supports direct color mode which specifies RGB with 24 bits/pixel.
