Page 18: Operating Principles & Methods
64CH Segment Driver For Dot Matrix LCD CS1B,CS2B CS3,RS DB0~DB7 MPU Read timing OPERATING PRINCIPLES & METHODS I/O Buffer Input buffer controls the status between the enable and disable of chip. Unless the CS1B to CS3 is in active mode, Input or output of data and instruction does not execute. Therefore internal state is not change. - Page 19 64CH Segment Driver For Dot Matrix LCD Function Instruction Status read (busy check) Data write (from input register to display data RAM ) Data read (from display data RAM to output register) Reset The system can be initialized by setting RSTB terminal at low level when turning power on, receiving instruction from MPU.
- Page 20 64CH Segment Driver For Dot Matrix LCD Display On/Off Flip-Flop The display on/off flip-flop makes on/off the liquid crystal display. When flip-flop is reset (logical low), selective voltage or non selective voltage appears on segment output terminals. When flip-flop is set (logic high), non selective voltage appears on segment output terminals regardless of display RAM data.
