DwRect 04h PE
Function
Draw Rectangles. The calculated pixel data
are stored into Video RAM (infinite com-
mand). Colour is defined by RECTCOL.
Source:
ULB input fifo with start and end point
n*([Xs,Ys], [Le,Xe,Ye]), n = number of
rectangles. Layer of endpoint ignored if
PPCMD_ULAY is set. Then
PPCMD_LAY is used instead of.
Registers
RECTCOL
PPCMD_LAY
PPCMD_ULAY
PPCMD_EN
IFIFO
Target:
Rectangular area of pixels between start
and end point in selected layer in Video
RAM.
PutTxtBM 05h PE
Notes:
RECTCOL or PPCMD changes apply after
new command only. Layer information in
pixel address can change with each line.
Only relevant bits of RECTCOL register
are used, depending on colour depht.
Store uncompressed pixel data with fixed
foreground or background Colour into
Video RAM (finite command).
Source:
ULB input fifo with n*[colour enable data]
n = (Xmax-Xmin+1)*(Ymax-Ymin+1)/32
Target:
Rectangular area of pixels between start
and end point in selected layer in Video
RAM. Background pixels are written only
if BGCOL_EN = ’1’.
