Product data sheet
7.9.1 Data pointer
The addressing mechanism for the display RAM is realized using the data pointer. This
allows the loading of an individual display data byte, or a series of display data bytes into
any location of the display RAM. The sequence commences with the initialization of the
data pointer by the load-data-pointer command. Following this command, an arriving data
byte is stored starting at the display RAM address indicated by the data pointer.
