Display Control
The display control instruction (Figure 14) includes the NL and DL bits.
NL1, NL0:
Designates the number of display lines. This value determines the LCD drive multiplexing duty
ratio (Table 15). The address assignment is the same for all display line modes.
DL3–DL1:
Doubles the height of characters on a specified line. The first, second, or third line is doubled in
height when DL1, DL2, or DL3 = 1, respectively. Two lines can be simultaneously doubled in a 4-line
display. Refer to the Double-Height Display section.

be scrolled (display-start line).
CT3–CT0:
Controls the LCD drive voltage (potential difference between V
CC
and V5) to adjust contrast
(Figure 16 and Table 16). For details, refer to the Contrast Adjuster section.
