The LCD segment-display register 2 is a 16-bit
read/write register. When the SEG_SEL bit (in the con-
trol register) is set to 1, the MAX1492/MAX1494 provide
direct access to individual LCD segments. The bits in
the LCD segment-display register determine if a seg-
ment is on or off. Write a 0 to this register to turn on a
segment and a 1 to turn off a segment.
