4.3 SET PAGE ADDRESS
This command is used to specify a page address equivalent to a row address for MPU access to
the display data RAM. A required bit of the display data RAM can be accessed by specifying its
page address and column address. Changing the page address causes no change in display.

4.4 COLUMN ADDRESS
This command specifies a display data RAM column address. The column address is incremented
by 1 each time the MPU accesses from the set address to the display data RAM. Thus, it is pos-
sible for the MPU to gain continuous access to only the data. This incrementing stops with address
80; the page address is not continuously changed.
