Target layer information is used by
PutBM, PutCP, PutTxtBM,
PutTxtCP any time. It is used by
DwLine, DwRect, DwPoly if
ULAY enabled.
Direction is relevant for PutBM,
PutCP, PutTxtBM and PutTxtCP
(0=horizontal, 1=vertical).
Mirror^b for PutBM, PutCP,
PutTxtBM, PutTxtCP (0h=with-
out mirroring, 1h=X-axis, 2h=Y-
axis, 3h=X- and Y-axis).

read access behavior:
0=internal buffered register,

a. Note! All colour data in the registers is right aligned (lsb) and depends on the colour depth/resolution.
b. The mirror funcionality means doubling at the limitation lines, which are defined by XMAX or YMAX (see
figure 1-2).
