Display Control
The display control instruction (Figure 13) includes the NL and DL bits.
NL:
Designates the number of display lines. This value determines the LCD drive multiplexing duty ratio
(Table 11). The address assignment is the same for all display line modes.
DL:
Doubles the height of characters on a specified line. The first line is doubled in height when DL = 1,
two lines can be simultaneously doubled in a 2-line display. Refer to the Double-Height Display section.
