CMOS Image Sensor supports analog gain function to amplify the pixel analog output
of CMOS Sensor. Available programmable range is 0 - 63. If the analog gain is too
large or too small, the dynamic range of sensor pixel output is not suitable for fine
scene. These registers(A7h,A8h) define the usable analog gain range (maximum and
minimum gain) of CIS for ISP to control R,G,B gain of CMOS Image Sensor within this
range. Available programmable range is 0 - 63 and the value of analog gain-Top limit
register must be larger than the value of analog gain-Bottom Limit register.
