Bits 15 to 5—Reserved
Bits 4 to 0—AC Line Number (ACLN): Set the line number where the LCD current-alternating
signal of the LCD module is toggled (unit: line).
Subtract 1 from the setting (0 to 31 (H'1F)).
Note: When the total line number of the LCD panel is even, set an even number so that toggling
is performed at an odd line.
Example: For toggling every 13 lines
ACLN = 13 – 1 = 12 = H'0C
25.2.16 LCDC Interrupt Control Register (LDINTR)
LDINTR specifies where to start the Vsync interrupt (LCDCI).
