EnaMemWR
[2]
Enable write access from host to RAM
EnaMemRD
[3]
Enable read access from RAM to host
DPDataSize
[4 to 17] Size of defect pixel data to read from RAM to host.
A maximum of 2000 defect pixels can be stored. To
get the number of defect pixels read out this value
and divide by 4.
In case of more than 2000 defect pixels,
DPDataSize is set to 2001 pixels
(DPDatasize of 8004 divided by 4 equals 2001
pixels) and BuildError flag is set to 1.
Defect pixel correction data is done with first 2000
defect pixels only.
AddrOffset
[18 to 31] Address offset to selected defect pixel data
