ST7528 Ver2.3 50/97 2007/1/3 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. A0 RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 1 1 Read data 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. During auto-increment, the column address wraps to 0 after the last column is written. Set Page Address Set Column Address Data Write Column = Column + 1 Data Write Continue ?
