When PD = 1, the power-down mode of the LCD driver is active:
When V = 0 the horizontal addressing is selected. The data is written into the DDRAM as

into the DDRAM as shown in
Y address is 5.
Bits Y2, Y1 and Y0 define the Y address vector of the display RAM (see
Table 6.
The X address points to the columns. The range of X is 0 to 127 (7Fh).
M[1:0] selects the multiplex rate (see
Table 7.
Bits D and E select the display mode (see
to icon mode.
