Box shadowing
In normal mode, writing a 1 to bit 12 (BSHAD1) of the COL setting in the 
VRAM causes a box shadow to appear around all characters following that COL. 
If COL bit 11 (BSHAD0) is 0, the color specified in the WBSHD register 
(x’007FA6’) appears on the top and left sides of the box and the color specified in 
the BBSHD register (x’007FA4’) appears on the bottom and right sides of the 
box. These positions are reversed if BSHAD0 is 1. Figure 7-25 shows an example 
of box shadowing. As shown in the figure, the right-hand border of the shadow 
box appears in the character field to the right of the shadowed text.
To output a box shadow to the 
right, output a space to the right 
of the text.
