NJU6635
(1-4-1)16-character 2-line Display
The NJU6635 has two kinds of addressing mode as “ Addressing mode 1 ” and “ Addressing mode 2 ”
which is determined by the Function Set Instruction (A=0 and 1).
“Addressing mode 1” uses sequential address of (00)H through (1F)H for front half 16-character and
last half 16-character. “Addressing mode 2 “ does not use sequential address like as (00)H through
(1F)H and (40)H through (4F)H for front half 16-character and last half 16-character respectively.
• Addressing mode 1: A=0

(1-4-2)The relation between DD RAM address and display position on the LCD shown below.
(Double Height Sized display Function).
Correspondence between DD RAM Address and display position on the LCD panel.
In case of double height size Display function, the address of DD RAM which is set as follows the
display, operates as 16-character 1-line and the addressing mode is ignored.
