13.3.2 Relationship between LCD RAM and Display
The relationship between the LCD RAM and the display segments differs according to the duty
cycle. LCD RAM maps for the different duty cycles are shown in figures 13.3 to 13.6.
After setting the registers required for display, data is written to the part corresponding to the duty
using the same kind of instruction as for ordinary RAM, and display is started automatically when
turned on. Word- or byte-access instructions can be used for RAM setting.
