Source Expansion Foreground Color Register

These bits always return 0 when read.
These 24 bits are optionally used to specify the foreground color for the color expansion of
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 source data,
BR02 is used to specify the foreground color for the color expansion of monochrome
pattern data.
Whether bits 7-0, 15-0 or 23-0 of this register are used in the color expansion process
depends upon the color depth to which the BitBLT engine has been set.
