10.2 Header Codes
The message can be a configuration word, an exposure, gain or calibration value. The camera’s interpretation of the header code
and the set-up code message are given in the table below. Defaults for each control bit are built in to the camera’s reset cycle,
and may be changed on-the-fly under host control.
10.3 Message content
The following Tables contain details of the data associated with each header code, and the number of valid data bits in each of
the registers. In all cases the full 12 bit message tail can be sent, the valid bits being packed to the lsb. (Normally, the unused bits
would be assigned zeroes.)
