(6) Display start line address set
This command is used to specify the display start line address of the DDRAM (refer to Figure 5).
If the display start line address is changed dynamically using this command, then screen scrolling, page swapping can
be performed.
See the function explanation in “Line address circuit”, for detail.
(7) ADC Select (Segment driver direction select)
This command can reverse the correspondence between the DDRAM column address and the segment driver output.
See the function explanation in “DDRAM and page/column address circuit”, for detail.
(8) Common driver direction select
This command can reverse the correspondence between the DDRAM line address and the common driver output. See
the function explanation in “Line address circuit”, for detail.
(9) Display data read
This command reads 8-bit data from the specified DDRAM address. Since the column address is automatically
incremented by +1 after each read ,the MPU can continuously read multiple-word data. One dummy read is required
immediately after the address has been set. See the function explanation in “Access to DDRAM and internal registers”
and “DDRAM and page/column address circuit”, for detail.
