Differences compared to SDA 525x according to preliminary specification 06/96:
1. UART is not supported.
2. RGB-outputs deliver a current instead of a voltage.
3. Instead of FIL1SLC/FIL2SLC/FIL3SLC only FIL3 is needed with changed external
device dimensions.
4. LCIN and LCOUT are not needed any more.
