Output Data Format
When outputting digital RGB data from the display unit (DU), the display data format is expanded
into the RGB666 format before output. The format at the time of output is as indicated in the
following table.

Endian Conversion
The display unit (DU) can perform big-endian/little-endian conversion according to the setting of
the DSEC bit in DSYSR.
The internal data format in the display unit (DU) is fixed at little-endian; by setting the DSEC bit
in DSYSR to 1, display data arranged in big-endian format in memory is converted into little-
endian format and read.
The units for endian conversion (byte/word) is determined by the setting of the PnDDF bit in
PnMR.
