0/0/0/PCI
Address Offset:
CC-CDh
Default Value:
0000h
Access:
RO, RW;
Size:
16 bits
This register enables various errors to generate an SMI DMI special cycle. When an
error flag is set in the ERRSTS register, it can generate an SERR, SMI, or SCI DMI
special cycle when enabled in the ERRCMD, SMICMD, or SCICMD registers respectively.
Note that one and only one message type can be enabled.

SMI on Processor Thermal Sensor Trip
(TSTSMI):
1: A SMI DMI special cycle is generated by
Processor when the thermal sensor trip
requires an SMI. A thermal sensor trip point
cannot generate more than one special cycle.
0: Reporting of this condition via SMI
messaging is disabled.

SMI on Multiple-Bit DRAM ECC Error
(DMESMI):
1: The Processor generates an SMI DMI
message when it detects a multiple-bit error
reported by the DRAM controller.
0: Reporting of this condition via SMI
messaging is disabled. For systems not
supporting ECC this bit must be disabled.

SMI on Single-bit ECC Error (DSESMI):
1: The Processor generates an SMI DMI special
cycle when the DRAM controller detects a single
bit error.
0: Reporting of this condition via SMI
messaging is disabled. For systems that do not
support ECC this bit must be disabled.
