Data_Out_Lower
Access: Read
Data_Out_Upper
Access: Read
Data Type: Sixteen bit word.
USAGE: Data from the system self test or the pixel dump command can be read out with these registers. The data can be read from 0x0d only, or
Once the pixel dump command is given, the sensor writes the address and the value for the first pixel into the Data_Out_Upper and Data_Out_Lower
registers. The MSB of Data_Out_Lower is the status bit for the data. If the bit is high, the data are NOT valid. Once the MSB is low, the data for that
particular read are valid and should be saved. The pixel address and data will then be incremented on the next frame. Once the pixel dump is
complete, the PixDump bit in register 0x0a should be set to zero. To obtain an accurate image to get the Pixel Dump image, the LED needs to be
turned on by changing the sleep mode of the configuration register 0x0a to always awake.

from 0x0d followed by 0x0c.
