OLOUR SET
With the Colour set (RGBSET) command the mapping from the 256-colour interface data is translated to the 4 kbyte
colour RAM data of the PCF8833 can be changed. The translation table must be changed, if necessary, before sending
256 colour data. For the red and green pixel 8 from the available 16 grey scales can be selected. For the blue pixel 4
from the 16 grey scales can be selected. The default or reset state of the colour mapping can be found in Table 32.
If the 256-to-4 kbyte colour mapping needs to be changed, the whole table must be sent. The mapping of colours is done
when writing data into the RAM, through the application of the Look-Up Table (LUT).

ARTIAL AREA
The Partial area command (PTLAR) sets the partial display area and displays the RAM content of this area. In the partial
Display mode the drive voltage can be reduced.
