This register controls the drawing frame foreground color. This color is used
for the object color of flat shading and foreground color of bitmap draw and
broken line draw. At bitmap drawing, all bits set to 1 are drawn in the color
set at this register.
Bits 15-0 FGC (Foreground Color)
Set foreground color value. In the indirect color mode, the lower 8 bits (bits 7-0) are used.
