Data Type: Six-bit number.
Usage:
This register is the CPI resolution of sensor for Y axis. Each step is equivalent to 38 counts based on x1 lens magnification.
Default value is 27 (CPI = 1026). Target CPI = 38 * CPI_Y. Recommended range : 16 ~ 63 (CPI = 608 ~ 2394).

Data Type: Eight-bit number.
Usage:
IQC means Image Quality Compliment. This register represents the fuzziness of a surface viewed by the sensor. The smaller
the index is, the easier for the sensor to have a good tracking on the surface. IQC ranges from 0 ~ 255.
IQC = 20
IQC = 50
IQC = 150
