5. FUNCTION DESCRIPTION& INSTRUCTION SET

In this module : It is work in single-scan, the RAM size is 8K, the address from 0000H-1FFFH.

the PIN HALT already connected to VDD, MD2&MD3=H, Column=32.

● Alter power on, it is necessary to reset. RESET is kept L between 5 clocks up (oscillation clock).

When HALT=L, the oscillation stops. The power supply for the LCD must now be turned off, to protect the LCD from DC bias.

The HALT function includes the RESET function.

The column /line counter and display register are cleared by RESET. (Other registers are not cleared.) Disable the display using the clear-display register.

The status must be checked before data or commands are sent. The MSB=0 status check must be done in particular. There is a possibility of erroneous operation due to a hard interrupt.

STA0 and STA1 must be checked at the same time. When a command is executed, data transmission errors may occur.

● The T6963C can only handle one byte per machine cycle (16 clocks). It is impossible to send more than two data in a machine cycle.

● When using a command with operand data, it important to send the data first, and then execute the command.

The character codes used by the T6963C are different from ASCII codes.

RAM Interface

The external RAM is used to store display data (text, graphic and external CG data).

With single-scan, text data, graphic data and external CG data can be freely allocated to the memory area ( 64KB max.)

With dual-scan, LCD Ⅰis allocteed to 0000H to 7FFFH (32 KB max.), LCDⅡis allocated to 8000H to FFFFH (32 KB max.). Text data, graphic data and external CG data can be freely allocated in LCD

. In LCDⅡ,the same address must be allocated as in LCDⅠ, except ad15. ad15 determines selection of LCDⅠor LCDⅡ.

It can be use the address decoded signals ce0( 0000 to 07FFH),ce1(0800 to 0FFFH) within 4 KB.ce0 and ce1 allow decoding of addresses in the ranges (0000 to 07FFH) and (0800 to 0FFFH) respectively within a 4-KB memory space.

(Note 1) it is necessary to check STA0 and STA1 at the same time.

There is a possibility of erroneous operation due to a hardware interrupt.

(Note 2) for most modes STA0/STA1 are used as a status check.

(Note 3) STA2 and STA3 are valid in Auto mode; STA0 and STA1 are invalid.

(Note 4) When using the MSB=0 command, a status read must be performed.

If a status check is not carried out, the T6963C can not operate normally, even after a delay time.

The hardware interrupt occurs during the address calculation period (at the end of each line).

If a MSB=0 command is sent to the T6963C during this period, the T6963C enters wait status.

If a status check is not carried out in this state before the next command is sent, There is the possibility that the command or data will not be received.

Offset Register Data Character Code Line Scan

T6963C assign External character generator, when character code set 80H to FFH in using internal character generator. Character code 00H to 80H assign External character generator, when External generator mode.

The senior five bits define the start address in external memory of the CG RAM area. The next eight bits represent the character code of the character. In internal CG ROM mode, character codes

00H to 7FH represent the predefined “internal” CG RAM mode, character codes 80H to FFH represent the user’s own “external” characters. In external CG RAM mode, all 256 codes from 00H to FFH can be used to represent the user’s own character. The three least significant bits indicate one of the eight rows of eight dots that define the character’s shape.

GRAPHIC TEXT

“OR” “AND” “EXOR”

(Note) Attribute functions can only be applied to text display, since the attribute data is placed in the graphic RAM area.

Attribute functions

The attribute operations are Reverse display, Character blink and Inhibit. The attribute data is written into the graphic area which was defined by the Set Control Word command. Only text display is possible in Attribute Function mode; graphic display is automatically disabled. However, the Display Mode command must be used to turn both Text and Graphic on in order for the

Attribute function to be available.

The attribute data for each character in the text area is written to the same address in the graphic area. The Attribute function is defined as follows.

-To prevent modules from degradation, do not operate or store them exposed directly to sunshine or high temperature/humidity.

10-5.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 operation. 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

10-6 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 sealed so as not to enter fresh air outside in it, and with no desiccant.

-Placing in a dark place where neither exposure 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.

10-7.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.
