Internal resistance division method only.
The output resistor is a resistor connected between one of the VLC0, VLC1, VLC2 and VSS pins, and either of
the SEG and COM pins.
Set VAON based on the following conditions.
<When set to the static display mode>
• When 2.0V≤ VLCD ≤ VDD ≤ 5.5 V: VAON = 0
• When 1.8V≤ VLCD ≤ VDD ≤ 3.6 V: VAON = 1
<When set to the 1/3 bias method>
• When 2.5V≤ VLCD ≤ VDD ≤ 5.5 V: VAON = 0
• When 1.8V≤ VLCD ≤ VDD ≤ 3.6 V: VAON = 1
<When set to the 1/2 bias method>
• When 2.7V≤ VLCD ≤ VDD ≤ 5.5 V: VAON = 0
• When 1.8V≤ VLCD ≤ VDD ≤ 3.6 V: VAON = 1
<When set to the 1/4 bias method>
• When 4.5V≤ VLCD ≤ VDD ≤ 5.5 V: VAON = 0
