6-5-5 COM Inversion
There are two types of inputs, COM signal serial input (EXTMODE=”L”) and external COM signal input (EXTMODE=”H”).

② EXTCOMIN input when the SCS signals is low.
M1：LC polarity inversion flag: If M1is "H" then VCOM="H" is output. If M1 is "L" then VCOM="L" is output.
※ 1 ： LC inversion polarity has been set by the rising timing of EXTCOMIN in internal circuit block as COMZ signal,
※2：The period of EXTCOMIN should be constant.
※ 3 ： LC inversion polarity has been set by the rising edge of EXTCOMIN.
※4：The period of EXTCOMIN should be constant.
M0
* 1：LC inversion has been changed by M1 flag statement.
* 2：The periods of plus polarity and minus polarity should be same length as much as possible.
