Description
GPWIO2_STS. Indicates if PME was caused by activity on GPWIO2.
0: No.
1: Yes.
Write 1 to clear.
For the PME to generate an SCI:
1)
2)
If F1BAR1+I/O Offset 15h[6] = 1 it overrides these settings and GPWIO2 generates an SMI and the status is reported in
F1BAR0+00h/02h[0].
GPWIO1_STS. Indicates if PME was caused by activity on GPWIO1.
0: No.
1: Yes.
Write 1 to clear.
For the PME to generate an SCI:
1)
2)
If F1BAR1+I/O Offset 15h[5] = 1 it overrides these settings and GPWIO1 generates an SMI and the status is reported in
F1BAR0+00h/02h[0].
GPWIO0_STS. Indicates if PME was caused by activity on GPWIO0.
0: No.
1: Yes.
Write 1 to clear.
For the PME to generate an SCI:
1)
2)
If F1BAR1+I/O Offset 15h[4] = 1 it overrides these settings and GPWIO0 generates an SMI and the status is reported in
F1BAR0+00h/02h[0].
Reserved. Must be set to 0.
USB_STS. Indicates if PME was caused by a USB interrupt event.
0: No.
1: Yes.
Write 1 to clear.
For the PME to generate an SCI, set F1BAR1+I/O Offset 12h[6] = 1 and F1BAR1+I/O Offset 0Ch[0] = 1. (See Note 2 in the
general description of this register above.)
THRM_STS. Indicates if PME was caused by activity on THRM#.
0: No.
1: Yes.
Write 1 to clear.
For the PME to generate an SCI, set F1BAR1+I/O Offset 12h[5] = 1 and F1BAR1+I/O Offset 0Ch[0] = 1, (See Note 2 in the
general description of this register above,)
SMI_STS. Indicates if PME was caused by activity on the internal SMI# signal.
0: No.
1: Yes.
Write 1 to clear.
For the PME to generate an SCI, set F1BAR1+I/O Offset 12h[4] = 1 and F1BAR1+I/O Offset 0Ch[0] = 1. (See Note 2 in the
general description of this register above.)
Ensure that GPWIO2 is enabled as an input (F1BAR1+I/O Offset 15h[2] = 0)
Ensure that GPWIO1 is enabled as an input (F1BAR1+I/O Offset 15h[1] = 0)
Ensure that GPWIO0 is enabled as an input (F1BAR1+I/O Offset 15h[0] = 0)
Set F1BAR1+I/O Offset 12h[10] = 1 and F1BAR1+I/O Offset 0Ch[0] = 1. (See Note 2 in the general description of this
register above.)
Set F1BAR1+I/O Offset 12h[9] = 1 and F1BAR1+I/O Offset 0Ch[0] = 1. (See Note 2 in the general description of this
register above.)
Set F1BAR1+I/O Offset 12h[8] = 1 and F1BAR1+I/O Offset 0Ch[0] = 1. (See Note 2 in the general description of this
register above).
