Voltage booster enable input:  
VBEN=0: disabled 
VBEN=1: enabled 
All VBENs 
MUST
 be connected while using multiple chips. 
LCD Bias Voltage 
LCD output signals 
These signals can be programmed as segments, commons, or both. 
(Depending on MODE[2, 1, 0] settings.) 
Voltage booster output.  VF is the maximum (negative) voltage output. 
All VFs 
MUST
 be tied together while using multiple chips. 
Maximum voltage booster output (VF) select 
VBSEL=0, VF = -2 x VDD 
VBSEL=1, VF = -3 x VDD
