Write Display Data
8-bit data of display data from the microprocessor can be written to the RAM location specified by the column address
and page address. The column address is increased by 1 automatically so that the microprocessor can continuously
write data to the addressed page.

Read Display Data
8-bit data from display data RAM specified by the column address and page address can be read by this Instruction.
As the column address is increased by 1 automatically after each this instruction, the microprocessor can
continuously read data from the addressed page. A dummy read is required after loading an address into the column
address register. Display data cannot be read through the serial interface.

ADC Select (Segment Driver Direction Select)
Changes the relationship between RAM column address and segment driver. The direction of segment driver output
pins can be reversed by software. This makes IC layout flexible in LCD module assembly.
