Display Line Control
NL3-0:
Set NL2–NL0 bits when SW = 0, and the NL3 bit when SW = 1 to specify the display lines.
Display lines change the liquid crystal display drive duty ratio. DDRAM or CGRAM address mapping
does not depend on the number of display lines.

CN1–CN0:
Set CN1–CN0 bits when SW = 1. When CN1–0 = 01, the display position is shifted by 16 dots
(two lines) below and display starts from COM17. When the liquid crystal is driven at low duty in the
system wait state, it can display partially at the center of the screen. For details, see the Partial-display-on
Function section.
When CN1–CN0 = 10, the display position is shifted by 8 dots (one line) above and second-line display
starts from COM1. The 8 dots of the first line are moved to the lowest edge of the display screen. The
output position of the lowest edge depends on the drive duty setting. In vertical smooth scrolling, PS1–PS0
bits can selectively fixed-display only the first to the third lines. Combining these functions enables the
fixed display of one line of the lowest edge. For details, see the Partial Smooth Scroll Display Function
section.
