4.3.4 White Balance

The white balance mode is saved in address 6 in RAM. If the internal WB mode is set, then the TMC-

6700/1000 series internally accumulates R and B white balance. If the external WB mode is set, then

the external WB-R and WB-B offset are loaded from address 2B (hex) and 2A (hex) respectively. WB-

R and WB-B offsets can be updated by accessing addresses 2B and 2A (hex). WB-R and WB-B in these

addresses are 2’s complement representation.
