24.3.10 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.
Initial value:
Notes: 1. The values set in HDCN and HTCN must satisfy the relationship of HTCN ≥ HDCN.

Also, the total number of characters of HTCN must be an even number. (The set value
will be an odd number, as it is one less than the actual number.)

Description
Horizontal Display Character Number
Set the number of horizontal display characters (unit:
character = 8 dots).
Specify to the value of (the number of display
characters) -1.
Example: For a LCD module with a width of 640 pixels.
Horizontal Total Character Number
Set the number of total horizontal characters (unit:
character = 8 dots).
Specify to the value of (the number of total characters) -
1.
However, the minimum horizontal retrace period is
three characters (24 dots).
Example: For a LCD module with a width of 640 pixels.

HDCN = (640/8) -1 = 79 = H'4F
HTCN = [(640/8)-1] +3 = 82 = H'52
In this case, the number of total horizontal
dots is 664 dots and the horizontal retrace
period is 24 dots.
