4.2 Windowing

Users are allowed to define window size as well as window location in PAS005B. Window size can range from

1x8 to 1288x1028 . The location of window can be anywhere in the pixel array. Window size and window

location is defined by register wcp_in, wcw_in, wrp and wrd: the wcp_in defines the starting column while wrp

defines the starting row of the window;. the wcw_in define the column width of the window and wrd define the

row depth of the window.
