LG240641-SFLYH6V -7- 4. COMMUNICATION WITH MPU 4.1 RAM Map The Display RAM is built in the module, and display data (text, graphic and CG data) is written to this display RAM. The built-in controller T6963C automatically reads the display RAM and sends the appropriate data to LCD drivers. The “Control Word Set” command (text home set, text area set, etc.) defines the RAM area which is read by the controller T6963C making the RAM map programmable by the user. If more than 1 screen can be stored in the RAM. Vertical scrolling and paging is easily performed by resetting text home and/or graphic home address. The 32K bytes built-in RAM is located at address 0000H ~ 7FFFH, and the following is an example of RAM mapping. 0000H Graphic RAM Area (0000H ~ 3BFFH) 3C00H Attribute RAM Area (3C00H ~ 3FFFH) 4000H Text RAM Area (4000H ~ 7BFFH) 7C00H CG RAM Area (7C00H ~ 7FFFH) 7FFFH CG RAM Offset register For 128 words, set data=”0FH” TH=1000H * 6 x 8 Font=48 screen * 8 x 8 Font=64 screen Text for 1024 characters GH=0000H * 6 x 8 Font=6 screen * 8 x 8 Font=8 screen 4.2 Status Read Status of the T6963C should be checked between all command and data in order to complete a communication cycle with the MPU. The status can be read from 8 bits data lines (D0 to D7) by setting C/D=“H”, /RD=“L”, /WR=“H” and /CE=“L”. The T6963C status word format is as follows: MSB STA7 D7 STA6 D6 STA5 D5 STA4 D4 STA3 D3 STA2 D2 STA1 D1 LSB STA0 D0 LG240641-SFLYH6V -8- 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. (Note 2) For most modes STA0/STA1 are used as a status check. (Note 3) STA2 and STA3 are used in Auto mode. Status checking flow a) Status check 1 b) Status check 2 STATUS AUTO MODE STATUS (*1) STA2=1(Read) or STA3=(Write) NO YES RETURN STA0=1 STA1=1 YES RETURN (*1) NO LG240641-SFLYH6V -9- 4.3 Setting data When using a command with operand data, first send the data, then send the command. Procedure for sending a command 1) Commnad with 1 byte data 2) Commnad with 2 bytes data Send Command Send Command Status check1 STA0,1 Status check1 STA0,1 Data write Data write Status check1 Status check1 Command write Data write END Status check1 Command write 3) Commnad with no data END Send Command Status check1 STA0,1 Command write END (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, Horizontal cursor position counted by “character”, 6 or 8 dots width. Y ADRS: 00H to 1FH, Vertical cursor position counted by “character”, 8 dots height. Note: Please note that the cursor position should be within actual display area. 5.1.2 Set Offset Register The Set Offset Register command is used to determine the character generator RAM area. The upper 5 bits in start address of CG area is set as the lower 5 bits of D1, and the uppe
