6.4 Line Address Circuit
As is shown in Figure 6
2, the line address circuit specifies the line address that corresponds to a COM output for
displaying the contents of display data RAM. The display start line address set command usually specifies the
highest line in the display (corresponding to the COM
0
output when in normal mode or the COM
63
output when in
inverted mode). Thus, there are 65 lines in the direction of incrementation of line address starting from the specified
display start line address.
The screen can be scrolled by dynamically changing the line address via the display start line address set
command.
