? 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
3
WR CE C/D D0-D7 T6963C status word format is following. MSB STA7 STA6 STA5 STA4 D7 D6 D5 D4
STA0 STA1 STA2 STA3 STA4 STA5 STA6 STA7 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 Error flag. Using screen peek/copy command Check the condition blink 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 H L H Status word STA3 D3 STA2 D2 STA1 D1 LSB STA0 D0
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 AUTO MODE STATUS STATUS STA0=1 STA2=1 STA1=1 NO (STA3=1) NO YES YES
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. ?
? Data Set
In T6963C, the data have been set and command executes. The order of procedure of command sending
