Only the Root Complex, the SMBus, and the D-Unit local devices have 

xxxxFERRUNCHDRLOG registers. 

• Local Correctable Error Status Register

The SoC provides the Local Correctable Error Status registers for the 

correctable errors associated with the SoC local interfaces. When a specific 

correctable error occurs in the SoC local interface, its corresponding bit in the 

Correctable Error Status register is set. Each error is individually masked by the 

Correctable Error Mask register.

Only the GbE and the memory controller local devices have correctable errors.

• Local Correctable Error Mask Register

• Local Correctable First/Next Error Status Register

The SoC provides the Local Correctable Error Log register for the errors 

associated with the SoC local interfaces. When a correctable error is detected 

by the SoC, the information related to the first/next error is stored in the 

xxxxFERRCORSTS/ **NERRCORSTS registers. FERR logs the first occurrence of 

an error, while NERR logs the subsequent occurrence of the errors. 

FERR/NERR do not log a masked error. The FERR log remains valid and unchanged from 

the first error detection until the clearing of the corresponding FERR Error bit in the 

Error Status register by the software. The xxxxERRCORSTS registers are only cleared 

by writing to the corresponding Local Error Status register. For example, clearing bit 0 

in DUNIT_ERRCORSTS clears the bit in this register and bit 0 in DUNIT_FERRCORSTS 

and DUNIT_NERRCORSTS.

• Local Correctable First Error Header Log Register 

The SoC provides the Local First Error Header Log register for the correctable 

errors associated with the SoC local interfaces. The Header log stores the 

header information of the associated first correctable error.

• Local Uncorrectable MCERR/IERR Register

The SoC P-Unit provides these registers for recording uncorrectable Machine 

Check Error (MCERR) and Internal Error (IERR) status.
