3.7.25 SCICMD – SCI Error Command Register (Device #0)
Address Offset: 67h
Default Value: 00h
Access: Read/Write
Size: 8 bits
This register enables various errors to generate a SCI cycle. When an Error Flag is set in the
ERRSTS register, it can generate a SERR or SMI cycle when enabled in the ERRCMD,
SMICMD, or SCICMD registers respectively. An error can generate one and only one Error
Special cycle. It is software’s responsibility to make sure that when an SCI error message is
enabled for an error condition, SERR and SMI Error Messages are disabled for that same error
condition.

3 SCI on GMCH/MCH Thermal Sensor Trip:
1 = An SCI Hub Interface Special cycle is generated by GMCH/MCH when the Thermal
Sensor Trip requires an SCI. A Thermal Sensor Trip Point cannot generate more
than one special cycle.
2 Reserved
1 SCI on Multiple-bit ECC Error:
1 = For systems that support ECC, this field must be set to 1.
0 = For systems that do not support ECC, this field must be 0.
0 SCI on Single-bit ECC Error:
1 = For systems that support ECC, this field must be set to 1.
0 = For systems that do not support ECC, this field must be 0.
