Address Counter (AC)
The Address Counter (AC) stores DDRAM/CGRAM addresses, transferred from IR. After writing into (reading
from) DDRAM/CGRAM. AC is automatically increased (decreased) by 1. When RS = 0 and R/W = 1, AC can be
read through ports DB0 - DB6.
Display Data RAM (DDRAM)
DDRAM stores display data of maximum 80 x 8 bits (80 characteristics). DDRAM address is set in the address
counter (AC) as a hexadecimal number. (Refer to fig-1).

Figure 1. DDRAM Address
1) 1-line Display
In the case of a 1-line display, the address range of DDRAM is 00H - 04H. An Extension driver will be used.
Figure 2 shows the example when a 40-segment extension driver is added.
2) 2-line Display
In the case of a 2-line display, the address range of DDRAM is 00H - 27H and 40H - 67H. An Extension driver will
be used. Figure 3 shows the example a 40 segment extension driver is added.
