Fault pixel correction error
RW
0x0
This bit is set when the CCDC module is unable to fetch
the required fault pixel table entry in time. Write 1 to clear
the error or end_of_frame clears it automatically for the
next frame.
For example, the current pixel being processed has
coordinates of 256/512 (256th line and 512th pixel in that
line) and it must be corrected. If the entry in the fault pixel
table that must be used has coordinates 256/256, then
the current pixel cannot be corrected since the correct
entry is not loaded in time.
Note that there is no error recovery mechanism in the
CCDC; if this bit is set at anytime in a frame, there are no
more fault pixels corrected in that frame. Firmware is
responsible for making sure that there is enough
bandwidth in the system to allow for loading of the fault
pixel table. Alternately, decreasing the frequency of the
fault pixels to be corrected enhances the chances of this
bit not being set.
0x0: No error
0x1: Error
