Loads previously stored FPN pixel coefficients from non-
volatile memory to FPGA SDRAM.
lfc
lfc
Before issuing this command, select the set you wish to load
with the SSN command:
0 = Factory set
1 to 4 = User sets
5 = Selects transfer from PC
FPN coefficients are only loaded from non-volatile memory
on: power-up, LFC, and LFS. They are not loaded by LUS.
wfc
Saves current values of PRNU pixel coefficients that are in
FPGA SDRAM to Flash memory or a PC file.
wpc
wpc
Before issuing this command, select the set you wish to write
with the SSN command:
0 = Factory set
1 to 4 = User sets
PRNU coefficients will be loaded by LPC, LFS, and
automatically at power-up
Coefficient use is enabled or disabled with the EPC command
Set 0 can only be written from factory mode
Provided so that user can generate their own coefficients to
send to the camera
