Core Logic Module - SMI Status and ACPI Registers - Function 1
32580B
Offset 04h-05h Second Level General Traps & Timers Reset Value: 0000h
PME/SMI Status Mirror Register (RO)
The bits in this register contain second level status reporting. Top level status is reported at F1BAR0+I/O Offset 00h/02h[9].
Reading this register does not clear the SMI. For more information, see F1BAR0+I/O Offset 06h.
15:6 Reserved.
5 PCI/ISA Function Trap. Indicates whether or not an SMI was caused by a trapped PCI/ISA configuration cycle.
0: No.
1: Yes.
To enable SMI generation for:
— Trapped access to ISA Legacy I/O register space set F0 Index 41h[0] = 1.
— Trapped access to F1 register space set F0 Index 41h[1] = 1.
— Trapped access to F2 register space set F0 Index 41h[2] = 1.
— Trapped access to F3 register space set F0 Index 41h[3] = 1.
— Trapped access to F4 register space set F0 Index 41h[4] = 1.
— Trapped access to F5 register space set F0 Index 41h[5] = 1.
4 SMI Source is Trapped Access to User Defined Device 3. Indicates whether or not an SMI was caused by a trapped I/O
or memory access to the User Defined Device 3 (F0 Index C8h).
0: No.
1: Yes.
To enable SMI generation, set F0 Index 82h[6] = 1.
3 SMI Source is Trapped Access to User Defined Device 2. Indicates whether or not an SMI was caused by a trapped I/O
or memory access to the User Defined Device 2 (F0 Index C4h).
0: No.
1: Yes.
To enable SMI generation, set F0 Index 82h[5] = 1.
2 SMI Source is Trapped Access to User Defined Device 1. Indicates whether or not an SMI was caused by a trapped I/O
or memory access to the User Defined Device 1 (F0 Index C0h).
0: No.
1: Yes.
To enable SMI generation, set F0 Index 82h[4] = 1.
1 SMI Source is Expired General Purpose Timer 2. Indicates whether or not an SMI was caused by the expiration of Gen-
eral Purpose Timer 2 (F0 Index 8Ah).
0: No.
1: Yes.
To enable SMI generation, set F0 Index 83h[1] = 1.
0 SMI Source is Expired General Purpose Timer 1. Indicates whether or not an SMI was caused by the expiration of Gen-
eral Purpose Timer 1 (F0 Index 88h).
0: No.
