Registers used by DispVram State object to control overexposure highlighting feature.
Control register sets highlight params like threshold, color, style.
Related register meaning is unknown at the moment, but it is also written on enable/disable by DispVram
At this moment we don't know how to enable highlights by just writing the registers. But while those are displayed - writing random number to control register changes both style and threshold of highlights.
