Monochrome Source Control Register
0: This causes the background and foreground colors for the color expansion of
monochrome source data to be specified by BR01 and BR02, respectively.
1: This causes the background and foreground colors for the color expansion of
monochrome source data to be specified by BR09 and BR0A, respectively.
Note: These bits are used only when the source data is monochrome.
These 3 bits are used to configure the BitBLT engine for the byte alignment of each
scanline’s worth of monochrome source data during a BitBLT operation, as each scanline’s
worth of monochrome source data is received.
Refer to the section describing the BitBLT engine for further details concerning the
requirements for how monochrome source data must be organized.
