Bit field name
R/W
Initial value
This register sets the drawing foreground color. This color is for the object color for flat shading and
foreground color for bitmap drawing and broken line drawing. All bits set to "1" are drawn in the
color set at this register.
8 bit color mode:
Bit 7 to 0 FGC8 (Foreground 8 bit Color)
Sets the indirect color for the foreground (color index code).
Bit 31 to 8 These bits are not used.
16 bit color mode:
Bit 15 to 0 FGC16 (Foreground 16 bit Color)
This field sets the 16-bit direct color for the foreground.
Note that the handling of bit 15 is different from that in ORCHID.
Up to ORCHID, bit 15 is "0" for other than bit map and rectangular drawing, but starting
with MB86R02 'Jade-D', the setting value is reflected in memory as is. This bit is also
reflected in bit 15 of the 16-bit color at Gouraud shading.
Bit 31 to 16 These bits are not used.
