Instruction is received from MPU to NT7108 for the display control. The following table shows various instructions. 13 of 30 11.Detailed Explanation The display data appears when D is 1 and disappears when D is 0. Though the data is not on the screen with D=0, it remains in the display data RAM. Therefore, you can make it appear by changing D=0 into D=1. SET ADDRESS (Y ADDRESS) Y address (AC0-AC5) of the display data RAM is set in the Y address counter. An address is set by instruction and increased by 1 automatically by read or write operations of display data. SET PAGE (X ADDRESS) X address (AC0-AC2) of the display data RAM is set in the X address register. Writing or reading to or from MPU is executed in this specified page until the next page is set. DISPLAY START LINE (Z ADDRESS) Z address (AC0-AC5) of the display data RAM is set in the display start line register and displayed at the top of the screen. When the display duty cycle is 1/64 or others (1/32-1/64), the data of total line number of LCD screen, from the line specified by display start line instruction, is displayed. 14 of 30 STATUS READ BUSY When BUSY is 1, the Chip is executing internal operation and no instructions are accepted. When BUSY is 0, the Chip is ready to accept any instructions. ON/OFF When ON/OFF is 1, the display is OFF. When ON/OFF is 0, the display is ON. RESET When RESET is 1, the system is being initialized. In this condition, no instructions except status read can be accepted. When RESET is 0, initializing has finished and the system is in usual operation condition. WRITE DISPLAY DATA Writes data (D0-D7) into the display data RAM. After writing instruction, Y address is increased by 1automatically. READ DISPLAY DATA Reads data (D0-D7) from the display data RAM. After reading instruction, Y address is increased by 1 automatically. 15 of 30 12.RELIABILITY Content of Reliability Test (wide temperature, -20℃~70℃ ℃) Environmental Test Test Item High Temperature storage Content of Test Endurance test applying the high storage temperature for a long time.
