SMI DMI Special Cycle (SMICMD_0_0_0_PCI) – Offset cc
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.

9 | 0b | RW | SMI on Multiple Bit Error (MC1_DMESMI) This bit is deprecated. |
8 | 0b | RW | Single Bit Error (MC1_DSESMI) This bit is deprecated. |
7 | 0b | RO | IBECC Uncorrectable Error (IBECC_UC) This bit is deprecated and kept for backwards compatibility. |
6 | 0b | RO | IBECC Correctable Error (IBECC_COR) This bit is deprecated and kept for backwards compatibility. |
5 | 0b | RW | SMI on FMHC Unsupported Request Event (FMUR) 1: The Host Bridge generates an SMI special cycle over DMI when FMHC reports an unsupported request event. |
4 | 0b | RW | SMI on FMHC CA Event (FMCA) SMI on FMHC CA event |
3 | 0b | RW | SMI on FMI Asynchronous Notification (FMIAN) SMI on FMI Asynchronous Notification error event |
2 | 0b | RW | SMI on FMHC Thermal Event (FMITHERMERR) SMI on FMHC thermal event |
1 | 0b | RW | SMI on Multiple Bit Error (MC0_DMESMI) 1: The Host generates an SMI DMI message when it detects a multiple-bit error reported by the DRAM controller. |
0 | 0b | RW | Single Bit Error (MC0_DSESMI) 1: The Host generates an SMI DMI special cycle when the DRAM controller detects a single bit error. |
