Reserved.
20
SMI_EXT
SMI from I/O Companion. ASMI generated when most recent serial packet had
SMI bit set. This bit ALWAYS represents the state of the SMI bit in the last serial
packet received. It cannot be written. To clear external SMI sources, proper external
controls must be sent (i.e., via the PCI bus).
19
SMI_PML2
SMI Power Management GLCP_LVL2. SSMI generated when GLCP_LVL2 (MSR
4C000019h) I/O register was read. Write 1 to clear, 0 has no effect.
18
SMI_PMCNT
SMI Power Management GLCP_CNT Mask. SSMI generated when GLCP_CNT
(MSR 4C000018h) I/O register was written. Write 1 to clear, 0 has no effect.
17
SMI_DBG
SMI Debug. ASMI generated due to debug event or PROCSTAT access. Write 1 to
clear, 0 has no effect.
16
SMI_ERR
SMI Error. ASMI generated due to error signal. Write 1 to clear, 0 has no effect.
15:5
RSVD
Reserved.
4
SMI_EXT_MASK
SMI from I/O Companion Mask. If clear, enables serial packets from external
device to generate an ASMI.
3
SMI_PML2_MASK
SMI Power Management GLCP_LVL2 Mask. If clear, enables power management
logic to generate an SSMI when GLCP_LVL2 I/O register (MSR 4C000019h) is read.
2
SMI_PMCNT_MASK
SMI Power Management GLCP_CNT Mask. If clear, enables power management
logic to generate an SSMI when GLCP_CNT (MSR 4C000018h) I/O register is writ-
ten.
1
SMI_DBG_MASK
SMI Debug Mask. If clear, enables debug logic to generate an ASMI.
0
SMI_ERR_MASK
SMI Error Mask. If clear, then any GLIU device error signal (including GLCP)
causes an ASMI.
