AD1 to AD5: ADATA display data
In addition to the 5 × 7, 5 × 8, or 5 × 9 dot matrix display data (MDATA), this IC supports direct display of the five
accessory display segments provided in each digit as ADATA. This display function does not use CGROM or CGRAM.
The figure below shows the correspondence between the data and the display. When ADn = 1 (where n is an integer
between 1 and 5) the segment corresponding to that data will be turned on.
