NEOTEC SEMICONDUCTOR LTD.NT7086PIN DESCRIPTION (CONTINUED)PIN I/O NAME FUNCTION INTERFACEControl input pin to fix the driver outputDISPOFFB I(SC1~SC80) to V0 level, during "Low" valueDisplayinput. LCD becomes non-selected by V0 levelOFF controloutput from every output of segment driversand every output of common drivers.ControllerCSICOM / SEGmodecontrolWhen CS = "Low", NT7086 is used as an80-bit segment driver.When CS = "High", NT7086 is set to an 80-bitcommon driverAccording to the input value of the AMS andthe CS pin, application mode of NT7086 isdiffers as shown below.VDD/VSSAMSIApplicationmode selectCS AMS Application mode COM/SEG0 04-bit parallelinterface mode0 11-bit serial interfacemodeSEG1 0Single typeapplication Mode1 1Dual type applicationmodeCOMVDD/VSSD1_SID,D2_DL,D3_DM,D4_DRI/O-In segment driver mode, these pins are usedas 4-bit data input pin (when 4-bit parallelinterface mode AMS= ”low”), or D1_SID isused as serial data input pin and other pins arenot used (connect these to VDD) (when 1-bitDisplayserial interface mode AMS= ”high”).data input/-In common driver mode, the data is shiftedserial inputfrom D2_DL (D4_DR) to D4_DR (D2_DL),data/ left ,when in single interface moderight data(AMS= ”Low”). In dual-type application case,input outputthe data are shifted from D2_DL and D3_DM(D4_DR and D3_DM) to D4_DR(D2_DL). Ineach case the direction of the data shift and theconnection of data pins are determined bySHL input (refer to NOTE 3, NOT 4).Controller12/04/2002 10/33
