Row 15, Column 13:
HORD — Horizontal Delay
This register controls the height of all displayed characters.
Row 15, Column 14:
CH[3:0] — Expand Characters by BRM Algorithm
CH[5:4] — Display Character Height Select

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.
These bits expand the 16-line characters using the binary rate
multiplier (BRM) algorithm. See
These two bits define the final height for the display characters. See

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].
