2. Precaution in use of LCD Module
(1) Avoid applying excessive shocks to the module or making any alterations or modifications to it.
(2) Don’t make extra holes on the printed circuit board, modify its shape or change the components of
LCD module.
(3) Don’t disassemble the LCM.
(4) Don’t operate it above the absolute maximum rating.
(5) Don’t drop, bend or twist LCM.
(6) Soldering: only to the I/O terminals.
(7) Storage: please storage in anti-static electricity container and clean environment.
(8) Don’t touch the elastmer connecter, especially insert a backlight panel (EL or CCFL)

As shown on next page
12.1(LED B/L)

12-2. KS0066 controller data
12-2.1 Function description
The LCD display Module is built in a LSI controller, the controller has two 8-bit registers, an instruction
register (IR) and a data register (DR).
The IR stores instruction codes, such as display clear and cursor shift, and address information for display
data RAM (DDRAM) and character generator (CGRAM). The IR can only be written from the MPU.
The DR temporarily stores data to be written or read from DDRAM or CGRAM. When address
information is written into the IR, then data is stored into the DR from DDRAM or CGRAM. By the
register selector (RS) signal, these two registers can be selected.

Busy Flag (BF)
Operation
Read data from DDRAM or CGRAM (DDRAM or CGRAM to DR)
When the busy flag is 1, the controller LSI is in the internal operation mode, and the next instruction will
not be accepted. When RS=0 and R/W=1, the busy flag is output to DB7.
The next instruction must
be written after ensuring that the busy flag is 0.
Address Counter (AC)
The address counter (AC) assigns addresses to both DDRAM and CGRAM
Display Data RAM (DDRAM)
This DDRAM is used to store the display data represented in 8-bit character codes. Its extended
capacity is 80×8 bits or 80 characters. Below figure is the relationship between DDRAM addresses and
positions on the liquid crystal display.

Character Generator ROM (CGROM)
The CGROM generate 5×8 dot or 5×10 dot character patterns from 8-bit character codes. See Table 2.
Character Generator RAM (CGRAM)
In CGRAM, the user can rewrite character by program. For 5×8 dots, eight character patterns can be
written, and for 5×10 dots, four character patterns can be written.
Write into DDRAM the character code at the addresses shown as the left column of table 1. To show the
character patterns stored in CGRAM.
