Combined with the SN1 and SN0 bits described in the Scroll Control section to select the first line
to be scrolled (display-start line).
CT3–CT0:
Controls the LCD drive voltage (potential difference between V
CC
and V5) to adjust contrast
(Figure 15 and Table 12). Refer to the Contrast Adjuster section.
