Active when Display Composer (DC) SEL=1

HSTART/HSTOP and VSTART/VSTOP determines the active part of the screen. The values here are specified in the native 640x480 display space. HSTART=0, HSTOP=640, VSTART=0, VSTOP=480 will set the active area to the full resolution. Note that the lower 2 bits of HSTART/HSTOP and the lower 1 bit of VSTART/VSTOP isn’t available. This means that horizontally the start and stop values can be set at a multiple of 4 pixels, vertically at a multiple of 2 pixels.
