Legend:
R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets
C = Only clearable bit
bit 7-3
bit 2-0
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).
