The TVP3030 is highly system integrated. It can be connected to the serial port of VRAM devices without
external buffering and connected to many graphics engines directly. It also supports the split shift-register
transfer operation, which is common to many industry standard VRAM devices. To aid in manufacturing test
and field diagnosis, several highly integrated test functions have been designed to enable simplified testing
of the palette and the entire graphics subsystem.
