bit 0

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).
