[Description]
Byte containing the value of the current contrast.

[Explanation]
Note that if you change this byte (valid values are 0-15 on HW1 and 0-31 on HW2), the contrast will not be changed.
You have to use <A HREF="$$LINK(system.h/OSContrastUp)">OSContrastUp</A> and <A HREF="$$LINK(system.h/OSContrastDn)">OSContrastDn</A> to actually change the contrast.
