The Frame Control Register 0 'BGEN' bit's function is shown in the Figure below. If you set the 'BGEN' bit as '0'
after selecting A's raster color as black, the raster color black will be displayed. But if you set the 'BGEN' bit as
'1', after selecting B's raster color as black, the raster color black becomes invisible, so the video back ground
color (gray) is displayed as if it is the raster color.
