Range

The array is divided into 16x16 blocks as

shown in Figure 1.1. each block is H24xV18 pixels.

The method for selecting vertical and horizontal

window region is the same. Each direction uses an

eight-bit register. Bit [7:4] selects the start block

location. Bit [3:0] selects the end block location. For

example, to select the shaded area as the active

region, use HWCTL=4cH,VWCTL=44H.

This window selection feature changes only the

assertion time of HREF and does not change the

pixel rate or the data rate. If the end location is

equal to or less than the start location, the window

size is from start location to the end of the right

most edge.
