Line address circuit
The line address circuit specifies the line address (as
shown Figure 5) relating to the COM output when the
contents of the DDRAM are displayed. The display start
line address, what is normally the top line of the display,
can be specified by Display start line address set
command. And Common driver direction select
command can be used to reverse the relationship between
the DDRAM line address and common output. For
example, as is shown in Table 5, the display start line
address corresponds to the COM0 output when the

Display data latch circuit
The display data latch circuit is a latch temporarily
stored the display data that is output to the LCD driver
circuit from the DDRAM.

common driver direction is normal, or the COM63

the display area is followed by the higher number line
addresses in ascending order from the display start line
address, corresponding to the duty cycle. This allows
flexible IC layout during LCD module assembly.
If the display start line address is changed dynamically
using the Display start line address set command,then
screen scrolling and page swapping can be performed.
