OPERATING PRINCIPALS AND METHODS 3.1 LCD Controller Display and Control Functions (T-6963C Controller) ■ Flowchart of Communications with MPU ● Status Read Before sending data (Read/Write) command, it is necessary to check the status. Status check Status of T6963C can be read from data lines. RD L WR H CE L C/D H D0-D7 Status word T6963C status word format is following. MSB STA7 STA6 STA5 STA4 STA3 D7 D6 D5 D4 D3 STA0 STA1 STA2 STA3 STA4 STA5 LSB STA0 D0 STA2 D2 STA1 D1 Check capability of command execution Check capability of data read/write Check capability of auto mode data read Check capability of auto mode data write Not use Check capability of controller operation 0 : Disable 1 : Enable 0 : Disable 1 : Enable 0 : Disable 1 : Enable 0 : Disable 1 : Enable 0 : Disable 1 : Enable STA6 Error flag. Using screen peek/copy command 0 : No error 1 : Error STA7 Check the condition blink 0 : Display off 1 : Normal display Note 1 : It is necessary to check STA0 and STA1 at the same time. The error is happened by sending data at executing command. Note 2 : The status check will be enough to check STA0/STA1. Note 3 : STA2/STA3 are valid in auto mode STA0/STA1 are invalid. Status checking flow STATUS STA0=1 STA1=1 YES AUTO MODE STATUS STA2=1 (STA3=1) YES NO NO RETURN RETURN Note 4 : It is impossible to save status check in the case of command of MSB0. To have the delay time cannot be save status check. The interrupt of hardware is happened at the end of lines. If command of MSB0 is sent in this period, the command executing is waited. The state of waiting doesn’t be known without to check status. The sending next command or data is disregarded or rewrites data of waiting command.
