Horizontal display start location is
specified using the 10 bits from HP9
to HP0.
HP9 to HP0 = (00000000002) and
(00000101112) setting is forbidden.

1 _{Πrepresents one line worth of spaces.}
Leave one line worth of space in the ver-
tical direction.
For example, 6 Π6 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 as follows:
×1 ^… N = 1 ×2 ^… N = 2
×3 ^… N = 3 ×4 ^… N = 4
