Core Logic Module (Continued)
5
EXT_SMI5 SMI Enable. When this bit is asserted, allow EXT_SMI5 to generate an SMI on negative-edge events.
0: Disable.
1: Enable.
Top level SMI status is reported at F1BAR0+00h/02h[10].
Second level SMI status is reported at bits 21 (RC) and 13 (RO).
4
EXT_SMI4 SMI Enable. When this bit is asserted, allows EXT_SMI4 to generate an SMI on negative-edge events.
0: Disable.
1: Enable.
Top level SMI status is reported at F1BAR0+00h/02h[10].
Second level SMI status is reported at bits 20 (RC) and 12 (RO).
3
EXT_SMI3 SMI Enable. When this bit is asserted, allow EXT_SMI3 to generate an SMI on negative-edge events.
0: Disable.
1: Enable.
Top level SMI status is reported at F1BAR0+00h/02h[10].
Second level SMI status is reported at bits 19 (RC) and 11 (RO).
2
EXT_SMI2 SMI Enable. When this bit is asserted, allow EXT_SMI2 to generate an SMI on negative-edge events.
0: Disable.
1: Enable.
Top level SMI status is reported at F1BAR0+00h/02h[10].
Second level SMI status is reported at bits 18 (RC) and 10 (RO).
1
EXT_SMI1 SMI Enable. When this bit is asserted, allow EXT_SMI1 to generate an SMI on negative-edge events.
0: Disable.
1: Enable.
Top level SMI status is reported at F1BAR0+00h/02h[10].
Second level SMI status is reported at bits 17 (RC) and 9 (RO).
0
EXT_SMI0 SMI Enable. When this bit is asserted, allow EXT_SMI0 to generate an SMI on negative-edge events.
0: Disable.
1: Enable.
Top level SMI status is reported at F1BAR0+00h/02h[10].
Second level SMI status is reported at bits 16 (RC) and 8 (RO).
Offset 28h-4Fh
Not Used
Reset Value: 00h
Offset
50h-FFh
The I/O mapped registers located here (F1BAR0+I/O Offset 50h-FFh) can also be accessed at F0 Index 50h-FFh. The pre-
ferred method is to program these registers through the F0 register space. Refer to Table 5-29 "F0: PCI Header and Bridge
Configuration Registers for GPIO and LPC Support" on page 199 for more information about these registers.
