Every time the sensor is reset, it resets this register. Without setting the register after sensor reset to the needed value I only get garbage data from the sensor. Since the possibility to reset the sensor is provided on the hardware and also used, the register has to be set after each sensor reset. Only the instance controlling the reset gpio pin "knows" the time, when the register should be initialized again, so it is asynchronously and not related to the standard camera activities. But since the stuff is _not_ documented, I can only speculate. Maybe it can be set to different values to achieve different things, currently I do not know.
