This command controls the liquid crystal driving
voltage V
cuit of the built-in liquid crystal power supply,
thereby adjusting the gradation of liquid crystal
display.
When data is set in the 4-bit register, the liquid
crystal driving voltage can take one of 16 voltage
states.

When the electronic volume function is not used,
set (A3, A2, A1, A0) = (0, 0, 0, 0).
This command sets addresses to write data into the
DD RAM, CG RAM and symbol register in the
address counter.
When the cursor is displayed, the cursor is dis-
played at the display position corresponding to the
DDRAM address set by this command.
A0 WR D7 D6 D5 D4 D3 D2 D1 D0
The settable address length is ADDRESS = 00H to
7FH.
Before writing data into the RAM, set the data
write address by this command. Next, when data is
written in succession, the address is automatically
incremented.
