Write Display Data
Data Read 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.
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.
