The FRAME_ECC Interface is a point-to-point connection between the SEM Controller and the FRAME_ECC primitive. The FRAME_ECC primitive is an output-only primitive that provides a window into the soft error detection function in the FPGA configuration system. The FRAME_ECC primitive and the behavior of the signals on this interface are described in Answer Record 54350 .
