Ø DL : Interface data length control bit
When DL = "High", it means 8-bit bus mode with MPU.
When DL = "Low", it means 4-bit bus mode with MPU. So to speak, DL is a signal to select
8-bit or 4-bit bus mode.
When 4-bit bus mode, it needs to transfer 4-bit data by two times.
Ø N : Display line number control bit
When N = "Low", it means 1-line display mode.
When N = "High", 2-line display mode is set.
Ø F : Display font type control bit
When F = "Low", it means 5 x 8 dots format display mode
When F = "High", 5 x11 dots format display mode.

l Set CGRAM Address
RS RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 1 AC5 AC4 AC3 AC2 AC1 AC0
Code
Set CGRAM address to AC.
This instruction makes CGRAM data available from MPU.
l Set DDRAM Address
RS RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
Code 0 0 1 AC6 AC5 AC4 AC3 AC2 AC1 AC0
Set DDRAM address to AC.
This instruction makes DDRAM data available from MPU.
When 1-line display mode (N = 0), DDRAM address is from "00H" to "4FH".
In 2-line display mode (N = 1), DDRAM address in the 1st line is from "00H" to "27H", and
DDRAM address in the 2nd line is from "40H" to "67H".

Description
The ST7066U dot-matrix liquid crystal display controller and driver LSI displays alphanumeric, Japanese kana characters, and symbols. It can be configured to drive a dot-matrix liquid crystal display under the control of a 4-or8-bit microprocessor. Since all the functions such as display RAM, character  generator,  and  liquid  crystal  driver,  required fordriving a dot-matrix liquid crystal display are internally provided on one chip,  a minimal system can be interfaced with this controller/driver.

Features
● 5 x 8 and 5 x 11 dot matrix possible
● Low power operation support:
   -- 2.7 to 5.5V
● Wide range of LCD driver power
   -- 3.0 to 10V
● Correspond to high speed MPU bus
   interface
   -- 2 MHz (when VCC = 5V)
● 4-bit or 8-bit MPU interface enabled
● 80 x 8-bit display RAM (80 characters max.)
● 13,200-bit character generator ROM for a
   total of 240 character fonts(5 x 8 dot or 5 x 11
   dot)
● 64 x 8-bit character generator RAM
   -- 8 character fonts (5 x 8 dot)
   -- 4 character fonts (5 x 11 dot)
● 16-common x 40-segment liquid crystal
   display driver
● Programmable duty cycles
   -- 1/8 for one line of 5 x 8 dots with cursor
   -- 1/11 for one line of 5 x 11 dots & cursor
   -- 1/16 for two lines of 5 x 8 dots & cursor
● Wide range of instruction functions:
   Display clear, cursor home, display on/off,
   cursor on/off, display character blink, cursor
   shift, display shift
● Automatic reset circuit that initializes the
   controller/driver after power on
● Internal oscillator with external resistors
● Low power consumption
● QFP80 and Bare Chip available
