unsigned integer
0 to 4095
AGC manual level value.
0 = minimum level
4095 (0x0FFF) = maximum level
6 checksum Frame check sequence.
The minimum and maximum pixel values (X0 and X1) that the AGC will display are
centered around the manual level value. The separation between X0 and X1 is determined
by the manual gain value. X0 and X1 are calculated as follows:
X0 = level + ceil (-(4095 - gain)/2)
X1 = level + ceil ( (4095 - gain)/2) + 1
