Display
The display is based on the requirements for a Level 1.5 Teletext and powerful
additional enhanced OSD features.
The display circuit reads the contents and attribute settings of the display
memory and generates the RGB data for a TV backend signal processing unit.
The display can be synchronized to external H/V sync signals (slave mode) or
can generate the synchronisation signals by itself (master mode). The display
can be synchronized to 50Hz as well as to 60 Hz systems. Interlaced display is
supported for interlaced sync sources and non-interlaced ones.
