LPDM/SCLMD
Last Pixel Draw/Move or Scale Up/Down Rectangular Object
If GE2D operates in Bresenham Line Draw acceleration mode (CMD (GE2D_CTL[23:22]) =
00), this bit defines the operation for last pixel of Bresenham line drawing.
0 = Last pixel of Bresenham line will be drawn.
1 = Last pixel of Bresenham line will not be drawn.
If GE2D doesn
’t operate in Bresenham Line Draw acceleration mode, this bit defines the
scale up/down for rectangular object.
0 = Scaling down object.
1 = Scaling up object.
[17]

0 = GE2D interrupt generation disabled.
1 = GE2D interrupt generation enabled.
[16]
