11.0 Suggested Software Register Programming
There are number of registers whose default values we
have been changed to make the sensor operational with
a Digital Still Camera. The registers, there suggested
new values (changes) and reason for there change are
detailed in

Switching External Resistor On for Lower
active power consumption
White Balance switched from Raw to Linear
gain mode .
Exposure Gain switched from Raw to Linear
2 gain mode
Negative Offset for Analog Signal Process-
