It appears to be a manufacturer inserted feature, as part of protection for
FPGA loaded firmware / bit-mask code.
"Bogus story: no Chinese backdoor in military chip
Today's big news is that researchers have found proof of Chinese
manufacturers putting backdoors in American chips that the military uses.
This is false. While they did find a backdoor in a popular FPGA chip, there
is no evidence the Chinese put it there, or even that it was intentionally
