Block Transfer with Update X/Y
Clipping
Figure 45-8. Relative Block Transfer From (1,0) to (4,4) Size (4,2)
If a drawing is rendered and needs to be duplicated along the X-axis or Y-axis, then a single
write to the TDGC_GOC will duplicate the drawing in the desired direction. This saves writing
actions to startx, starty, endx, endy, color and logic operation registers and results in a faster
rendering.
Figure 45-9. Block Transfer with Update X Two Times
This function disables drawing outside the selected rectangular field. The clipping x and y coor-
dinates are defined by the values, in pixel units, programmed in four clipping vertex registers
TDGC_CXMINR, TDGC_CXMAXR, TDGC_CYMINR, TDGC_CYMAXR. Clipping is enabled by
setting CEN bitfield in TDGC_CCR.
