5.1 Data transfer

The SED1521 use the A0, /RD and /WR signals to tran sfer data between the system and MPU and internal register. The combinations used are given in the table below. To read the contents of display data RAM, twice access of read instruction is needed. In fist access, data in display data RAM is latched into output register. In second access, MPU can read data which is latched. That is, to read the data in display data RAM, it needs dummy read. But status read does not need dummy read. A0 /RD /ER Function 1 0 Instruction Input 0 0 1 Status read ( busy check ) 1 0 Data write ( from input register to display data RAM) 1 0 1 Data read ( from display data RAM to output register)

5.2 Reset

System reset can be initialized by setting RSTB terminal at low level when turning power on, receiving instruction from MPU. When RSTB becomes low, following procedure is occurred. 1 . D i s p l a y o f f 2. Display start line register become set by 0. (Z-address 0) While RSTB is low level, no instruction except status read can be accepted. Reset status appears at DB4. After DB4 is low, any instruction can be accepted. The Conditions of power supply at initial power up are shown in table 1.

5.3 Busy Flag

Busy flag indicates that SED1521 is operating or not operating. When busy flag is high, NJU6450 is in internal operating. When busy flag is low, SED1521 can accept the data or instruction. DB7 indicates busy flag of the SED1521.

5.4 Display On/Off Flip-Flop

The display on/off flip-flop makes on/off the liquid crystal display. When flip-flop is reset (logical low), selective voltage or non selective voltage appears on segment output terminals. When flip-flop is set (logical high), non selective voltage appears on segment output terminals regardless of display RAM data. The display on/off flip-flop can change status by instruction. The display data at all segments disappear while RSTB is low. The status of the flip-flop is output to DB5 by status read instruction.

5.5 X Page Register

X page register designates page of the internal display data RAM. It has not count function. An address is set by instruction.

5.6 Y Address Counter

Y address counter designates address of the internal display data RAM. An address is set by instruction and is increased by 1 automatically by read or write operations of display data.

5.7 Display Data RAM

Display data RAM stores a display data for li quid crystal display. To express on state of dot matrix of liquid crystal display, write data 1. The other way, off state write 0.

5.8 Display Start Line Register

The display start line register indicates address of display data RAM to display top line of liquid crystal display. Bit data (DB<0:5>) of the display start line set instruction is latched in display start line register. It is used for scrolling of the liquid crystal display screen.

Note 1: Condensation of water is not permitted on the module. Note 2: The module should be inspected after 1 hour storage in normal conditions (15~35 oC,45~65%RH) 11. HANDLING PRECAUTION 11-1. MOUNTING METHOD The panel of the LCD module consis ts of two thin glass plates with polarizes which easily get damaged since the module is fixed by utilizing fitti ng holes in the printed circuit board. Extreme care should be taken when handling the LCD modules. 11 -2. CAUTION OF LCD HANDLING & CLEANING When cleaning the display surface. Use so ft cloth with solvent (recommended below) and wipe lightly. -Isopropyl alcohol -Ethyl alcohol -Tri chlorotri fluoroethane Do not wipe the display surface with dry or hard materials that will damage the polarizes surface. Do not use the following solvent: -Water -Ketone -Aromatics 11-3.CAUTION AGAINST STATIC CHARGE The LCD modules use COMS LSI drivers. So we recommend that you connect any unused input terminal to Vdd or Vss, do not input any signa ls before power is turned on and ground your body. work/assembly table. And assembly equipment to protect against static electricity. 11-4.PACKAGING -Modules use LCD elements, and must be treated as such avoid intense shock and falls from a height -To prevent modules from degradation, do not operate or store them exposed directly to sunshine or high temperature/humidity.

HEBEI GEM-TECH ELECTRONICS CO., LTD. P/N: GTG-160324-BTCL2C PAGE: 15 11-5.CAUTION FOR OPERATION -It is indispensable to drive LCM within the specified voltage limit since the higher voltage than the limit shortens LCM life. -Response time will be extremely delayed at lower temperature than the operating temperature range and on the other hand at higher temperature LCD show dark color in them. However those phenomena do not mean malfunction or out of order with LCD, which will come back in the specified operating temperature range. -If the display area is pushed hard during ope ration. Some font will be abnormally displayed but it resumes normal condition after turning off once. -A slight dew depositing on terminals is a cause for Electro-chemical reaction resulting in terminal open circuit. Under the maximum operating temperature, 50%RH or less is required 11-6 STORAGE In the case of storing for a long period of time (for instance, for years) for the purpose or replacement use. the following ways are recommended -Storage in a polyethylene bag with the opening s ealed so as not to enter fresh air outside in it, and with no desiccant. -Placing in a dark place where neither expos ure to direct sunlight nor light is, keeping temperature in the specified storage temperature range. -Storing with no touch on polarizes surface by the anythingelse. (it is recommended to store them as they have been contained in the inner container at the time of delivery from us. 11-7.SAFETY -It is recommendable to crash damaged or unnecessary LCD into pieces and wash off liquid crystal by using solvents such as acetone and ethanol, which should be burned up later. -When any liquid crystal leaked out of a da maged glass cell comes in contact with your hands, please wash it off well with soap and water. 12.PRECAUTION FOR USE 12-1.A limit sample should be provided by the both parties on an occasion when the both parties agree its necessity. Judgement by a limit sample shall take effect af ter the limit sample has been established and confirmed by the both parties. 12-2.On the following occasions, the handling of problem should be decided through discussion and agreement between representative of the both parties -When a question is arisen in this specification. -When a new problem is arisen which is not specified in this specifications. -When an inspection specification change or operating condition change in customer is reported to GEM-TECH, and some problem is arisen in this specification due to the change. -When a new problem is arisen at the cust omer’s operating set for sample evaluation in the customer size.
