2.11 Character Size Control Command
This command can set the character size in line units (in both the horizontal and vertical directions).
Because this is a 2-byte command, it must be input in 16-bit units even when successively input.

Function
Vertical 1 dot: 1H, horizontal 1 dot: 1t dot (minimum size)
Vertical 1 dot: 2H, horizontal 1 dot: 2t dots
Line specification control bits
These bits specify the character size in line units, and control which line is to be specified.
Character size control bit
This bit selects the character size in two steps.
Display with two character size specified
Example of display screen
Line 0: minimum size (vertical 18H/horizontal 12 dots)
Line 1: 2 times
(vertical 36H/horizontal 24 dots)
Line 2: minimum size
External video signal, etc.
Line 3: 2 times
Line 4: minimum size
Line 5: 2 times
Line 6: 2 times
Line 7: minimum size
Lines 8 to 11 are omitted
because they overflow from the screen.
The size in the vertical direction (the number of horizontal scanning lines) is the size in field units.
