10. Video Subsystem
10-1. Introduction
UP-5300 adapts the VGA controller (MN89305) to allow the following
type of LCD panel.
LM10V33 (640
×
480 XRGB DSTN 256 color)
The display data format of the MN89305 is 16 bpp. In the 16-bpp
format Data in memory directly becomes R, G and B data, and makes
it possible to select between the R(5)+G(6)+B(5) and R(5)+G(5)+B(5)
formulation. For the area of less than 6bits, 5-bit data is positioned to
the 5 higher-order bits. This data is output passing through the gray
scale engine block and half frame control block to the LCD.
UP-5300 connects a PCI bus as the interface, and uses 2 chips of
EDO DRAM configured in 256K
×
16 as graphic memory so that the
total capacity is 1M bytes.

On the MN89305, it is possible to select up to three kinds of initializa-
tion parameters of the LCD panel on the VGA BIOS. When the panel
described above is to be used, the following settings must be re-
quired.
