CONTROL DATA
DR: 1/2 BIAS DRIVE OR 1/3 BIAS DRIVE SWITCHING CONTROL DATA.
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
