EXT_SMI[7:0] are external SMIs, meaning external to the Core Logic module.
Bits [23:8] of this register contain second level of SMI status reporting. Top level status is reported in F1BAR0+I/O Offset
00h/02h[10]. Reading bits [23:16] clears the second and top levels. If the value of the status bits must be read without clearing
the SMI source (and consequently deasserting SMI), bits [15:8] can be read instead.
Description
SLP_EN SMI Status. Indicates whether or not an SMI was caused by a write of 1 to the ACPI SLP_EN bit (F1BAR1+I/O
Offset 0Ch[13]).
0: No.
1: Yes.
To enable SMI generation, set F1BAR1+I/O Offset 18h[9] to 1 (default).
THT_EN SMI Status. Indicates whether or not an SMI was caused by a write of 1 to the ACPI THT_EN bit (F1BAR1+I/O
Offset 00h[4])
0: No.
1: Yes.
To enable SMI generation, set F1BAR1+I/O Offset 18h[8] to 1 (default).
SMI_CMD SMI Status. Indicates whether or not an SMI was caused by a write to the ACPI SMI_CMD register
(F1BAR1+I/O Offset 06h).
0: No.
1: Yes.
A write to the ACPI SMI_CMD register always generates an SMI.
Reserved. Must be set to 0.
EXT_SMI7 SMI Status. (Read to Clear) Indicates whether or not an SMI was caused by assertion of EXT_SMI7.
0: No.
1: Yes.
To enable SMI generation, set bit 7 to 1.
EXT_SMI6 SMI Status. (Read to Clear) Indicates whether or not an SMI was caused by an assertion of EXT_SMI6
0: No.
1: Yes.
To enable SMI generation, set bit 6 to 1.
EXT_SMI5 SMI Status. (Read to Clear) Indicates whether or not an SMI was caused by an assertion of EXT_SMI5.
0: No.
1: Yes.
To enable SMI generation, set bit 5 to 1.
EXT_SMI4 SMI Status. (Read to Clear) Indicates whether or not an SMI was caused by an assertion of EXT_SMI4.
0: No.
1: Yes.
To enable SMI generation, set bit 4 to 1.
EXT_SMI3 SMI Status. (Read to Clear) Indicates whether or not an SMI was caused by an assertion of EXT_SMI3.
0: No.
1: Yes.
To enable SMI generation, set bit 3 to 1.
EXT_SMI2 SMI Status. (Read to Clear) Indicates whether or not an SMI was caused by an assertion of EXT_SMI2.
0: No.
1: Yes.
To enable SMI generation, set bit 2 to 1.
EXT_SMI1 SMI Status. (Read to Clear) Indicates whether or not an SMI was caused by an assertion of EXT_SMI1.
0: No.
1: Yes.
To enable SMI generation, set bit 1 to 1.
