PON VRH3 VRH2 VRH1 VRH0
VRH[3:0] Set the amplifying rate (1.6 ~ 1.9) of Vci applied to output the VREG1OUT level, which is a
reference level for the VCOM level and the grayscale voltage level.
VCIRE: Select the external reference voltage Vci or internal reference voltage VCIR.
VCIRE=0
VCIRE =1
External reference voltage Vci (default)
Internal reference voltage 2.5V
