The display window registers (DSWR (HDS/HDE/VDS/VDE)) are 16-bit readable/writable
registers that specify the horizontal and vertical output timing for the display screen.
1. Horizontal Display Start Position (Bits HDS): Field that specifies the horizontal display start
position in dot-clock units.
2. Horizontal Display End Position (Bits HDE): Field that specifies the horizontal display end
position in dot-clock units.
3. Vertical Display Start Position (Bits VDS): Field that specifies the vertical display start
position in dot-clock units.
4. Vertical Display End Position (Bits VDE): Field that specifies the vertical display end position
in dot-clock units.
