Description

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.

5PCI/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.

4SMI 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.

3SMI 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.

2SMI 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.

1SMI 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.

0SMI 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.

1:Yes.

To enable SMI generation, set F0 Index 83h[0] = 1.
