3.1. SDM ECC Error Message Bits

The SDM ECC error message bits store the error message when the Agilex™ 5 device detects an SDM ECC error.

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