I/O Procedure
• Input timing (command input, display data input)
• Output timing (display code data output)
Note) If CS is set at "L" level when 8-bit read-out is not complete, and CS is set at "H" level again, then

read-out operation is executed, uncomplete data will be output continually and the remaining
read-out data will be zero.

Code data or arbitrator data indicated by the address pointer is always output, provided
that the SOE command has already been input.
