Unimplemented: Read as ‘0’
LCDCST<2:0>: LCD Contrast Control bits
Selects the resistance of the LCD contrast control resistor ladder
Bit Value = Resistor ladder
000 = Minimum Resistance (Maximum contrast). Resistor ladder is shorted.
001 = Resistor ladder is at 1/7th of maximum resistance
010 = Resistor ladder is at 2/7th of maximum resistance
011 = Resistor ladder is at 3/7th of maximum resistance
100 = Resistor ladder is at 4/7th of maximum resistance
101 = Resistor ladder is at 5/7th of maximum resistance
110 = Resistor ladder is at 6/7th of maximum resistance
111 = Resistor ladder is at maximum resistance (Minimum contrast).
