Bit 7-3: These bits determine the column end position of Window 1on the 15*30 OSD screen.
Bit 2-0: R/G/B – These bits control the background color of Window 1. Refer to Table for color selection.
Note: Window 1 control registers occupy column 0-2 of row 15, Window 2 from column 3-5, Window 3 from
6-8 and Window 4 from 9-11. The function of Window 2- 4 control registers is the same as Window 1.
Window 1 has the highest priority, and the Window 4, the least. The higher priority color will take
over on the overlap window area.
If the start address of the row/column is greater than the end address, the window will not be
displayed.
Out of range setting (over 15 rows or 30 columns range) will cause abnormal operation.
