HORD — Horizontal Delay
These bits define the horizontal starting position for character display.
The 8-bit gives 256 steps, with each step increment of six dots shift to
the right on the monitor screen. The maximum value of HORD is
decided by the rightmost character not exceeding the next leading
edge of PHSYNC.
18.8.3.4 Character Height Control Register
This register controls the height of all displayed characters.

CH[3:0] — Expand Characters by BRM Algorithm
These bits expand the 16-line characters using the binary rate
multiplier (BRM) algorithm. See Figure 18-13 for some examples.
CH[5:4] — Display Character Height Select
These two bits define the final height for the display characters. See
Figure 18-14 for illustration.

Character Display Size
Display size is same size as expanded font by CH[3:0].
The default value is 00.
Display size is double size of expanded font by CH[3:0].
Display size is triple size of expanded font by CH[3:0].
