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)

12-3. KS0066 controller data
12-3.1 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.
RS R/W Operation
0 0 IR write as an internal operation (display clear, etc.)
0 1 Read busy flag (DB7) and address counter (DB0 to DB7)
1 0 Write data to DDRAM or CGRAM (DR to DDRAM or CGRAM)
1 1 Read data from DDRAM or CGRAM (DDRAM or CGRAM to DR)
Busy Flag (BF)
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.
High bits Low bits

Example: 2-Line by 16-Character 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.
