Pattern/Source Expansion Background Color &
These bits always return 0 when read.
These 24 bits are used to specify the background color for the color expansion of either
monochrome pattern data only, or both monochrome pattern data and monochrome source
data (depending on the setting of bit 27 of BR03). When bit 27 of BR03 is set so that this
register is used in the color expansion of monochrome pattern data only, BR09 is used to
specify the background color for the color expansion of monochrome source data.
These 24 bits are also optionally used to specify the key color for whichever form of color
transparency is selected via bits 16-15 of BR04 (depending on the setting of bit 27 of
BR03).
Whether bits 7-0, 15-0 or 23-0 of this register are used in both the color expansion and color
transparency processes depends upon the color depth to which the BitBLT engine has
been set.
