3.1. SDM ECC Error Message Bits

The SDM ECC error message bits store the error message when the Intel® Agilex™ detects an SDM ECC error.

The SDM ECC error message contains information about the sector address and type of the error. You can retrieve the contents of the error message from the generic_sdm_data_out signal of the Advanced SEU Detection Intel® FPGA IP.
