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. xRAM 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 K byte max ). Recommend 0000H TEXT AREA 0C00H GRAPHIC AREA 1800H CG RAM AREA 2000H Flowchart of communications with MPU (1) Status Read A status check must be performed before data is read or written. Status check The Status of T6963C can be read from the data lines. L RD WR H CE L C/D H Do to D7 H The T6963C status word format is as follows: MSB LSB STA7 STA6 STA5 STA4 STA3 STA2 STA1 STA0 D7 D6 D5 D4 D3 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 D2 D1 D0 0:Disable 1:Enable 0:Disable 1:Enable 0:Disable 1:Enable 0:Disable 1:Enable ᧩ 0:Disable 1:Enable Error flag. Used for Screen Peek and Screen copy 0:No error STA6 commands. 1:Error 0:Disable off STA7 Check the blink condition 1:Normal display (Note 1) It is necessary to check STA0 and STA1 at the same time. STA5 Check controller operation capability 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 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 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 date will not be received. (2) Setting date When using the T6963C, first set the data, then set the command. Procedure for sending a command (a)The case of 1 date (Note) (b)The case of 2 data When sending more than two data, the last datum (or last two data) is valid. ᧪COMMAND DEFINITIONS COMMAND REGISTERS SETTING SET CONTROL WORD MODE SET DISPLAY MODE CURSOR PATTERN SELECT DATA AUTO READ/WRITE DATA READ/WRITE SCREEN PEEK CODE D1 D2 00100001 00100010 00100100 01000000 01000001 01000010 01000011 X address Date Low address Low address Columns Low address Columns Y address 00H High address High address 00H High address 00H ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ 1000×000 1000×001 1000×011 1000×100 10000××× 10001××× 10010000 1001××10 1001××11 100101×× 100110×× 100111×× 10100000 10100001 10100010 10100011 10100100 10100101 10100110 10100111 10110000 10110001 10110010 11000000 11000001 11000010 11000011 11000100 11000101 11100000 Data ᧩ Data ᧩ Data ᧩ ᧩ FUNCTION Set Cursor Pointer Set Offset Register Set Address Pointer Set Text Home Address Set Text Area Set Graphic Home Address Set Graphic Area OR mode EXOR mode AND mode Text Attribute mode Internal CG ROM mode External CG RAM mode Display off Cursor on, blink off Cursor on, blink on Text on, graphic off Text off, graphic on Text on, graphic on 1-line cursor 2-line cursor 3-line cursor 4-line cursor 5-line cursor 6-line cursor 7-line cursor 8-line cursor Set Data Auto Write Set Data Auto Read Auto Reset ᧩ ᧩ ᧩ ᧩ ᧩ Data Write and Increment ADP Data Read and Increment ADP Data Write and Decrement ADP Data Read and Decrement ADP Data Write and Nonvariable ADP Data Read and Nonvariable ADP ᧩ ᧩ Screen Peek X : invalid COMMAND CODE D1 D2 FUNCTION SCREEN COPY 11101000 ᧩ ᧩ Screen Copy BIT SET/RESET 11110××× ᧩ ᧩ Bit Reset 11111××× 1111× 001 1111× 001 1111× 010 1111× 011 1111× 100 1111× 101 1111× 110 1111× 110 ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ ᧩ Bit Set Bit 0 (LSB) Bit 1 Bit 2 Bit 3 Bit 4 Bit 5 Bit 6 Bit 7 (MSB) X: invalid ᧪Setting registers CODE HEX.

The T6963C has a 16-bit address bus as follows. 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.

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 cannot accept any other commands. The Auto Reset command must be sent to the 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.

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.

FUNCTION OPERAND 11100000 E0H Screen Peek ᧩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 HEX. FUNCTION OPERAND 11101000 E8H Screen Copy ᧩ 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.)
