Allocation of text, graphics and external character generator RAM can be made easily and the display window can be moved freely within the allocated memory range. ·RAM Interface The external RAM is used to store display data( text, graphic and external CG data ). It can be freely allocated to the memory area( 8 Kbyte max ).

Status check The Status of T6963C T6963C can be read from the data lines. RD L WR H CE L C/D H Do to D7 H The T6963C T6963C status word format is as follows: MSB LSB STA7 STA6 STA5 STA4 STA3 STA2 STA1 STA0 D7 D6 D5 D4 D3 D2 D1 D0 STA0 Check command execution capability STA1 Check data read/write Capability STA2 Check Auto mode data read capability STA3 Check Auto mode data write capability STA4 Not used STA5 Check controller operation capability STA6 Error flag. Used for Screen Peek and Screen copy commands. STA7 Check the blink condition 0:Disable 1:Enable 0:Disable 1:Enable 0:Disable 1:Enable 0:Disable 1:Enable 0:Disable 1:Enable 0:No error 1:Error 0:Disable off 1:Normal display (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. Status Checking flow (a)(b) (Note 4) When using the MSB=0 command, a Status Read must be performed. If a status check is not carried out, the T6963C T6963C cannot 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 T6963C during this period, the T6963C 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 date will not be received. (2)Setting date When using the T6963C T6963C, first set the data, then set the command. Procedure for sending a command (a)The case of 1 date (b)The case of 2 data (Note) When sending more than two data, the last datum (or last two data)is valid.

The cursor position can only be moved by this command. Data read/write from the MPU never changes the cursor pointer. X ADRS and Y ADRS are specified as follows. X ADRS 00H to 4FH (lower 7 bits are valid) Y ADRS 00H to 1FH (lower 5 bits are valid) Single-Scan X ADRS 00 to 4FH Y ADRS 00H to 0FH ( 2)Set Offset Register The offset register is used to determine the external character generator RAM area. The T6963C T6963C has a 16-bit address bus as follows. T6963C 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, character codes 00H to 7FH represent the predefined "internal" CG ROM characters, and codes 80H to FFH represent the user's own "external" characters. In external CG ROM mode, all 256 codes from 00H to FFH can be used to represent the user's own characters. The three least significant bits indicate one of the eight rows of eight dots that define the character's shape.

The display mode does not change until the next command is sent. The logical OR, EXOR, AND of text or graphic display can be displayed. In Internal Character Generator mode, character codes 00H to 7FH are assigned to the built-in character generator ROM. The character codes 80H to FFH are automatically assigned to the external character generator RAM. (Example) (Note)Attribute functions can only be applied to text display, since the attribute data is placed in the graphic RAM area. Attribute function 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. Attribute RAM 1byte × d3 0 0 0 1 1 1 d2 0 1 0 0 1 0 d1 0 0 1 0 0 1 d0 0 1 1 0 1 1 × × × FUNCTION Normal display Reverse display Inhibit display Blink of normal display Blink of reverse display Blink of inhibit display d3 d2 d1 X: invalid d0 Display mode CODE 10010000 1001xx10 1001xx11 100101xx 100110xx 100111xx FUNCTION OPERAND Display off Cursor on, blink off Cursor on, blink on Text on, graphic off Text off, graphic on Text on, graphic on X: invalid (Note)It is necessary to turn on "Text display" and "Graphic display" in the following cases. a)Combination of text/graphic display b)Attribute function Cursor pattern select CODE FUNCTION OPERAND 10100000 1-line cursor 10100001 2-line cursor 10100010 3-line cursor 10100011 4-line cursor 10100100 5-line cursor 10100101 6-line cursor 10100110 7-line cursor 10100111 8-line cursor When cursor display is ON, this command selects the cursor pattern in the range 1 line to 8 lines. The cursor address is defined by the Cursor Pointer Set command. Data Auto Read/Write CODE HEX. FUNCTION OPERAND 10110000 B0H Set Data Auto Write 10110001 B1H Set Data Auto Read 10110010 B2H Auto Reset The command is convenient for sending a full screen of data from the external display RAM. After setting Auto mode, a Data Write (or Read) command is need not be sent between each datum. A Data Auto Write (or Read) command must be sent after a Set Address Pointer command. After this command, the address pointer is automatically incremented by 1 after each datum. In Auto mode, the T6963C T6963C cannot accept any other commands. The Auto Reset command must be sent to the T69963C T69963C after all data has been sent, to clear Auto mode. (Note)A Status check for Auto mode (STA2, STA3 should be checked between sending of each datum. Auto Reset should be performed after checking STA3=1 (STA2=1.)

Data Write/Data Read should be executed after setting address using Set Address Pointer command. The address pointer can be automatically incremented or decremented using this command. (Note)This command is necessary for each 1-byte datum. Refer to the following flowchart. Screen Peek CODE 11100000 HEX. E0H FUNCTION Screen Peek OPERAND e This command is used to transfer 1 byte of displayed data to the data stack; this byte can then be read from the MPU by data access. The logical combination of text and graphic display data on the LCD screen can be read by this command. The status (STA6) should be checked just after the Screen Peek command. If the address determined by the Set Address Pointer command is not in the graphic area, this commands is ignored and a status flag (STA6) is set. Refer to the following flowchart. Screen Copy CODE 11101000 HEX. E8H FUNCTION Screen Copy OPERAND This command copies a single raster line of data to the graphic area. The start point must be set using the Set Address Pointer command. (Note 1) If the attribute function is being used, this command is not available. (With Attribute data is graphic area data.)
