Draw Access 2
If draw access is attempted when signal CL1 is low, the display access is suspended to perform draw
access (Figure 30). After the draw access, the display access is performed again. As a result, even if draw
access is attempted asynchronously, at least one of the display accesses will be performed.
Display Access by First Line Data Transfer
If no draw access is attempted, display access for the first line is performed when signal FLM is high and
CL1 is low. The display access for the second line is performed when signal CL1 is low (Figure 31).
