TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC DOT MATRIX LCD CONTROL LSI The T6963C is an LCD controller designed to be used with LCD control driver LSIs and data display memories. The device has an 8-bit parallel data bus and control lines for reading or writing through an MPU interface. It oo N, can be directly connected to a TMPZ-80. —— It has a 128-word character generator ROM which can Ww se << control an external display RAM of up to 64 Kbytes. ZB —— 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. QFP67-P-1420-0.80 The device supports a very broad range of LCD formats Weight: 1.2g (typ.) by allowing selection of different combinations via a set of programmable inputs. It can be used in text, graphic and combination text-and-graphic modes, and includes various attribute functions.

e@ After 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. @ STAO 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. 1997-04-07 5/46

@ 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 (64 KB max). With dual-scan, LCDI is allocated to 0000H to 7FFFH (32 KB max), LCDII is allocated to 8000H to FFFFH (32 KB max). Text data, graphic data and external CG data can be freely allocated in LCDI . In LCDII, the same addresses must be allocated as in LCDI, except ad15. ad15 determines selection of LCDI or LCDII. It can be use the address decoded signals ce0 (0000 to O7FFH), ce1 (0800 to OFFFH) within 4 KB. ce0 and ceT allow decoding of addresses in the ranges (0000 to 07FFH) and (0800 to OFFFH) respectively within a 4-KB memory space.

There is a possibility of erroneous operation due to a hardware interrupt. (Note 2) For most modes STAO/STA1 are used as a status check. (Note 3) STA2 and STA3 are valid in Auto mode; STAO and STA1 are invalid. 1997-04-07 9/46

a) b) NO NO STAZ=1 (Read) STAa=1 (Write) Yes Yes (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 will not be received. (2) Setting data When using the T6963C, first set the data, then set the command. Procedure for sending a command a) The case of 1 data b) The case of 2 data [==] [==] CD [==] (Note) When sending more than two data, the last datum (or last two data) is valid. 1997-04-07 10/46

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 ROM characters, and 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 characters.

This command is used for writing data from the MPU to external display RAM, and reading data from external display RAM to the MPU. 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. Address pointer = 1000H Data =AAH ‘AH is written in 1000H address. ‘Address pointer is 1001H 1997-04-07 22/46

© Screen Peek CODE FUNCTION OPERAND T1100000 | EOH [Screen Peck SCS SC Ci” 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 command is ignored and a status flag (STA6) is set. Refer to the following flowchart. yes [en | (Note) This command is available when hardware column number and software column number are the same. Hardware column number is related to MD2 and MD3 setting. Software column number is related to Set Text Area and Set Graphic Area command. 1997-04-07 23/46

@ Screen Copy CODE FUNCTION OPERAND 11101000 | 8H [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.) (Note 2) With Dual-Scan, this command cannot be used (because the T6963C cannot separate the upper screen data and lower screen data). Refer to the following flowchart. ll <n > (#1) Status check STA6=1 (*2) Status check STAO/1=1 YES (Note) This command is available when hardware column number and software column number are the same. Hardware column number is related to MD2 and MD3 setting. Software column number is related to Set Text Area and Set Graphic Area command. 1997-04-07 24/46
