The width of each register in the Color Space Converter control register map is 32 bits.
The coefficient and summand registers use integer, signed 2’s complement numbers.
To convert from fractional values, simply move the binary point right by the number
of fractional bits specified in the user interface.
The control data is read once at the start of each frame and is buffered inside the
MegaCore function, so the registers can be safely updated during the processing of a
frame.

Bit 0 of this register is the Go bit, all other bits are unused. Setting this bit to 0 causes
the Color Space Converter MegaCore function to stop the next time control information
is read. Refer to
Bit 0 of this register is the Status bit, all other bits are unused. Refer to
