Special Image Functions
Available functions are mono tone, gray scale, sepia, and negative. Sepia Cb/Cr Value bits and
special image functions threshold value register can be used when you want to change Cb and Cr
sense of image for sepia mode. Mono value bit and special image functions threshold value
register are can be used when you want to change a threshold value determining white and black
level at mono tone.

If function mode is mono tone image and this pin is high, using this
register can change a threshold value determining white and black
level. After set SPESEL to 24h, set SPETHVALUE register to a value
which you want.
If you want other image tone, but not sepia, using this bits and
SPETHVALUE register is possible. First, set SPESEL to 42h and set
SPETHVALUE register to a Cb value which you want. Final, set
SPESEL to 82h and set SPETHVALUE register to a Cr value which
you want.
