(6) RAM Address Setup
The RAM Address Setup command sets an address
into the Address counter to write data into
DDRAM, CGRAM and Symbol register.
When the cursor display is ON, the cursor is
located at a position corresponding to the DDRAM
address set by this command.
1 The 00H to 7FH address length can be set.
To write data in the RAM, set the data write
address by this command. When the
subsequent data is written continuously, the
address is automatically incremented.
