DR is the 1/2 bias drive or 1/3 bias drive switching control data bit. It is used to select either 1/2 bias drive or 1/3 bias drive. When this pin is set to “0” the 1/2 bias drive is selected. When this pin is set to “1’, the 1/3 bias drive is selected. Please refer to the table below for the DR settings. DR Drive Type “0” 1/2 Bias Drive “1” 1/3 Bias Drive SC: SEGMENT ON/OFF CONTROL DATA SC is the Segment ON/OFF Control Data Bit. It is used to select the state of the segments. If the SC is set to “0”, then the Segment Display are turned ON, however, if the SC is set to “1”, the Display State is OFF. Please refer to the table below. SC Display State “0” ON “1” OFF It should be noted that when the segments are turned off via the SC setting (SC=”1”), the segments are turned off the outputting of the segment OFF waveforms from the Segment Output Pins. BU: NORMAL MODE/POWER SAVING MODE CONTROL DATA BIT BU is the Normal Mode/Power Saving Mode Control Data Bit. It is used to select either the Normal Mode or the Power saving Mode. When the BU is set to “0”, the Normal Mode is enabled, however, if the BU is set to “1”, the Power saving Mode is active. It should be noted that under the Power Saving Mode, the Oscillation (OSC Pin) is stopped and the Common and Segment Pins output Vss levels. BU Mode Selected “0” Normal Mode “1” Power Saving Mode

The display is turned off (SG1 to SG52, COM1 to COM3 are all set to “Low” Level) by setting the /INH pin to “Low” at the same time the power is applied. (Please note that when the /INH Pin is set to “LOW”, the OSC Pin is not active.) As a result of this, irrelevant display at the time of the power ON can be eliminated if not prevented by transferring the serial data from the controller while the display is OFF and by setting the /INH pin after the transfer is completed. Please refer to figures below.
