6.1.5 Page Address Circuit
The page address of the DDRAM is specified through the Page Address Set
Command. The page address must be specified again when changing pages to
perform access. Page address 8 is the page for the RAM region used only by the static
indicators, and only the display data D0 is used.
6.1.6 Line Address Circuit
The line address circuit specifies the line address corresponding to the common output
when the DDRAM contents are displayed. Using the display start line address set
command, the normally the top line of the display can be specified (which is the COM0
output when the common output mode is normal, and the COM63 output for the
EM65565A when the common output mode is reversed. The display area is a 65 lines
area for the EM65565A from the display start line address.
If the line address is changed dynamically using the display start line address set
command, screen scrolling, page swapping, etc. can be performed.
