2.14.59 ECC Second Address Register - ECCSAR

When the ECC Error Phase register (bits 6:4 of the ECCCSR) is non-zero (indicating

that an error has been captured) and the failing transaction included a dual address

cycle (DAC), the ECCSAR register indicates the contents of the

P_AD[31:0]

bus (for

64- and 32-bit buses) for the second address phase of the transaction that included the

error. When the ECC Error Phase register is zero, the contents of this register are

undefined.

Note:

Registers that store information from the failing transaction always store information

directly from the bus (uncorrected), even when correction of the error is possible.

Note:

The

“ECC Control and Status Register - ECCCSR”

“ECC First Address Register -

ECCFAR”

“ECC Second Address Register - ECCSAR”

, and

“ECC Attribute Register -

ECCAR”

report the actual transaction that has the error. For example, when the Split

Completion of an original Outbound Read request has an error, the information

regarding the Split Completion is reported.
