The configuration of the registers is given in
All the registers are defined by a subaddress of 7 bits: bit Mode refers to the mode
which is used with the I
each register.
Bit Mode, used only with the I

The default values correspond to a VESA 1280
This register controls the clamp level for the RGB channels. The relationship between
the programming code and the level of the clamp code is given in

Each register is programmed independently, by giving its subaddress
and its content.
All the registers are programmed one after the other, by giving this initial
condition (XXX1 1111) as the subaddress state; thus, the registers are
changed following the predefined sequence of 16 bytes (from
subaddress 0000 to 1101).
