25.2.10 LCDC Horizontal Character Number Register (LDHCNR)
LDHCNR specifies the LCD module's horizontal size (in the scan direction) and the entire scan
width including the horizontal retrace period.
Bits 15 to 8—Horizontal Display Character Number (HDCN): Set the number of horizontal
display characters (unit: character = 8 dots).
Subtract 1 from the setting (0 to 252 (H'FC)).
Example: For an LCD module with a width of 640 pixels
Bits 7 to 0—Horizontal Total Character Number (HTCN): Set the number of total horizontal
characters (unit: character = 8 dots). Subtract 1 from the setting (3 to 255 (H'FF)).
The minimum horizontal retrace period is three characters (24 dots).
The values set in HDCN and HTCN must satisfy the relationship of HTCN ≥ HDCN + 3.
HTCN should be set to an odd number value when using a color STN 16-bit I/F module.
Example: For an LCD module with a width of 640 pixels

HDCN = (640/8) – 1 = 79 = H'4F
HTCN = [(640/8) – 1] + 3 = 82 = H'52
