ST7036
2-line display (N3=0,N = 1) (Figure 9)
Case 1: When the number of display characters is less than 40 x 2 lines, the two lines are displayed from the
head. Note that the first line end address and the second line start address are not consecutive. For example,
when just the ST7036 is used, 20 characters x 2 lines are displayed. See Figure 9.
When display shift operation is performed, the DDRAM address shifts. See Figure 10.
