the internal voltage generator is switched off.
The proper value for the VLCD is a function of the Liquid Crystal Threshold Voltage (Vth) and of the Multiplexing
Rate. A general expression for this is:

For MUX Rate m = 65 the ideal V

is:

Temperature Coefficient
As the viscosity, and therefore the contrast, of the LCD are subject to change with temperature, there's the need
to vary the LCD Voltage with temperature. The STE2001 provides the possibility to change the VLCD in a linear
fashion against temperature with four different Temperature Coefficient selectable through the TC0 and TC1
bits.
