at a location that enables a complete picture to be stored in a 4 Mbyte memory boundary (A [21:0]). A [31:22] has a

The size register defines the height and width of the LCD screen.

Screen width divided by 16. Holds screen x-axis size in pixels, divided by 16. For black-and-white panels (1 bpp),
XMAX
XMAX[0] is ignored, forcing the x-axis of the screen size to be a multiple of 32 pixels/line. A value of zero in this bit
field is reserved.
Note: The maximum supported panel size is 800x600 pixels. Therefore the maximum value for this bit field is 0x32.
19–10
Reserved, must be cleared.
9–0
Screen height. Specifies the height of the LCD panel in terms of pixels or lines. The lines are numbered from 1 to
YMAX
YMAX for a total of YMAX lines. A value of zero in this bit field is reserved.
Note: The maximum supported panel size is 800x600 pixels. Therefore the maximum value for this bit field is 0x258.
22.3.3
LCDC Virtual Page Width Register (LCD_VPW)
The virtual page width register defines the width of the virtual page for the LCD panel.
