T6963CFG
DOT MATRIX LCD CONTROLLER LSI
The T6963CFG 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 can be directly connected to a TMPZ-80. It has a 128-word character generator ROM which can control an external display RAM of up to 64 Kbytes. 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. The device supports a very broad range of LCD formats 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. The T6963CFG is lead (Pb)-free (Sn-Ag) product.

Functional Definition
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. STA0 and STA1 must be checked at the same time. When a command is executed, data transmission errors may occur. The T6963CFG 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 T6963CFG are different from ASCII codes.

The relationship between number of row / column and oscillation clock (Fig. 2)
The frequency of the crystal oscillator is adjusted by the following formula. fOSC : Frequency of oscillation fSCP : Frequency of shift clock (fSCP = fOSC / 2) fR : Frequency of Frame M : Number of characters on one line (number of dots on one line 8 M) For all font sizes (e.g. 7 x 8, 6 x 8, 5x 8) the oscillation frequency remains constant. N : Number of rows (duty = 1 / 8N) 8M

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, LCD I is allocated to 0000H to 7FFFH (32 KB max), LCD II is allocated to 8000H to FFFFH (32 KB max). Text data, graphic data and external CG data can be freely allocated in LCD I. In LCDII, the same addresses must be allocated as in LCD I, except ad15. ad15 determines selection of LCD I or LCD II. 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.

Flowchart of communications with MPU
(1) Status Read
A status check must be performed before data is read or written. The Status of T6963CFG can be read from the data lines. RD L WR H CE L C/D H D0 to D7 Status word The T6963CFG status word format is as follows:
MSB STA7 D7 STA6 D6 STA5 D5 STA4 D4 STA3 D3 STA2 D2 STA1 D1 LSB STA0 D0
STA0 STA1 STA2 STA3 STA4 STA5 STA6 STA7
Check command execution capability Check data read / write capability Check Auto mode data read capability Check Auto mode data write capability Not used Check controller operation capability Error flag. Used for Screen Peek and Screen copy commands. 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: Display 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.

T6963CFG
Note 4: When using the MSB = 0 command, a Status Read must be performed. If a status check is not carried out, the T6963CFG 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 T6963CFG during this period, the T6963CFG 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 T6963CFG, first set the data, then set the command.
Note: When sending more than two data, the last datum (or last two data) is valid.

T6963CFG
T6963CFG 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. The three least significant bits indicate one of the eight rows of eight dots that define the character' s shape.

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 10110000 10110001 10110010 Hex. B0H B1H B2H Function Set Data Auto Write Set Data Auto Read Auto Reset Operand
This 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 T6963CFG cannot accept any other commands. The Auto Reset command must be sent to the T6963CFG after all data has been sent, to clear Auto mode.

Screen Peek
Code 11100000 Hex. E0H Screen Peek Function Operand
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.
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.

Screen Copy
Code 11101000 Hex. E8H Screen Copy Function 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.) Note 2: With Dual-Scan, this command cannot be used (because the T6963CFG cannot separate the upper screen data and lower screen data). Refer to the following flowchart.
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.
