4.2. Field descriptions

These are the fields in the MBIST Datalog Register in a configuration with parity:

Datalog[86:76]

11 bits that contain the failing address.

Datalog[75:4]

72 bits that contain an XOR between failing data and correct data. All bits at1’b1 are failing.

Datalog[3:0]

4 bits that contain the expected data seed.

These are the fields in the MBIST Datalog Register in a configuration without parity:

Datalog[78:68]

11 bits that contain the failing address.

Datalog[67:4]

64 bits that contain an XOR between failing data and correct data. All bits at1’b1 are failing.

Datalog[3:0]

4 bits that contain the expected data seed.
