SRAM ECC Log Register — SELOGR

The SRAM ECC Log Register is responsible for logging the error types detected on the

local memory bus. One error can be detected and logged. The error type is logged

(single-bit or multi-bit) along with the syndrome that indicated the error. For a

single-bit error, software can read this syndrome and determine which bit had the error

in order to perform scrubbing. For a multi-bit error, the syndrome will not match an

entry in the H-Matrix and thus, is not correctable (see

Table 346, “Syndrome Decoding”

on page 522

).

The error recorded in SELOGR corresponds to the address in SECAR and SECUAR.
The SELOGR comprise read-only bits and only have meaning if SMCISR[0] or

SMCISR[1] is non-zero. For more details on error handling, see

Section 8.3.3, “Error

Correction and Detection” on page 519

.

Upper ECC Address

— The upper 4 bits of the 36-bit ECC Address is stored in this 4-bit field when an

ECC error is logged. For example, the lower 32 bits are logged in the SRAM ECC Address Register

(SEAR).
