Section 26 LCD Controller (LCDC)
26.3.12 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 upper and lower panels, e.g. 480 for a 640 x 480 panel.
