Function
Enable right side background
shadow.
cf. If BSL=1 and BSCUL=1 and
LnATTR.ENSHn=1, character’s
15
BSR right bottom shadow is shifted to
right side by 1dot unit.
It acts continued until current
character’s right side chacter’s
BSR is set to 1.

Table 17-5 VRAM (bit15~0) function
Note: if (BSL = 1) & (BSCUL = 0) & (LnATTR,ENSHn = 1),
then the right bottom shadow of font character is shifted to
1 dot right side. This shadow effect will continue until that
(BSR) of adjacent character attribution become (BSR = 1).
