Architecture Overview (Continued)
The CS9210 converts the digital RGB output of the
CS5530 I/O companion chip to the digital output suitable
for driving a dual-scan color STN (DSTN) flat panel LCD.
It connects to the digital RGB output of a GXm processor
or 55x0 and drives the graphics data onto a dual-scan flat
panel LCD. It can drive all standard dual-scan color STN
flat panels up to 1024x768 resolution. Figure 1-3 shows
an example of a CS9210 interface in a typical GXm Inte-
grated Subsystem.
