Function
Registers
Store an compressed bitmap (TGA run-
length coded) in Video RAM (finite com-
mand).
Source:
IFIFO with n*[bitmap RLE data]
n depends on compression factor. If
number of decompressed pixels is not suffi-
cient
(Xmax-Xmin+1)*(Ymax-Ymin+1), PE
will not become ready and waits for data.

Target:
Video RAM area which is defined by
{Xmax, Xmin}, {Ymax, Ymin},
PPCM_LAY and PPCMD_MIR. Pixel with
IGNORCOL_COL are not written if
IGNORCOL_EN = ’1’.
Draw Lines. The calculated pixel data are
stored into Video RAM (infinite com-
mand). Colour is defined by LINECOL.
Source:
ULB input fifo with start and end points
n*([Xs,Ys], [Le,Xe,Ye]), n = number of
lines. Layer of end point ignored if
PPCMD_ULAY is set. Then
PPCMD_LAY is used instead of.
LINECOL
PPCMD_LAY
PPCMD_ULAY
PPCMD_EN
IFIFO
Target:
Line of pixels between start and end point
in selected layer in Video RAM.
Notes:
LINECOL or PPCMD changes apply after
new command only. Layer information in
pixel address can change with each line.
Only relevant bits of LINECOL register are
used, depending on colour depht.
