(S) represents one line worth of space
When register RAMERS is set to "1", do not stop the
display clock. There is no need to reset because there
is no register for this bit.
Leave one line worth of space in the
vertical direction.
For example, 6 (S) 6 indicates two sets
of 6 lines with a line of spaces between
lines 6 and 7.
A line is 18 ✕ N horizontal scan lines.
N is determined by the character size in
the vertical direction
