The Segment and Grid Outputs are fixed to VDD. Test Pin 0 or floating : the Normal Operation Mode 8 1:the Test Mode is active Display Line Select Pin This pin is used to select the number of display lines when the 9 Power is ON, Reset or Resetting. 0: 1 line is selected (N=”0”)* 1: 2 lines are selected (N=”1”)* Duty Select Pin These pins set the duty ratio. The duty ratio is determined by the 10, 11 number of Grid. Read/Write (Write) Signal Pin Under the M68 Parallel Data Transfer Mode (R/W), this pin functions as the Data Transfer Select Pin. 0: Write Function 1: Read Function 12 Under the i80 parallel data Transfer Mode (/WR), this pin is Write Enable Pin. It writes data at the rising edge of this signal. Under the Serial Transfer Mode, the Read or Write function is selected by instruction and this pin is connect to either “H” or “L”. Register Select/Strobe Pin Under the Parallel Transfer Mode is selected, this pin acts as the Register Select Pin. 13 0:Instruction Register (IR) 1: Data register (DR) Under Serial Data Transfer Mode, this pin acts as the Strobe Input Pin.
