25.2.12 LCDC Vertical Display Line Number Register (LDVDLNR)
LDVDLNR specifies the LCD module's vertical size (for both scan direction and vertical
direction). For a DSTN panel, specify an even number at least as large as the LCD panel's vertical
size regardless of the size of the up and down panels, e.g. 480 for a 640 × 480 panel.
