Description
User Defined Device 3 (UDEF3) Idle Timer Enable. Turn on UDEF3 Idle Timer Count Register (F0 Index A4h) and gener-
ate an SMI when the timer expires.
0: Disable.
1: Enable.
If an access occurs in the programmed address range, the timer is reloaded with the programmed count.
UDEF3 address programming is at F0 Index C8h (base address register) and CEh (control register).
Top level SMI status is reported at F1BAR0+I/O Offset 00h/02h[0].
Second level SMI status is reported at F0 Index 85h/F5h[6].
User Defined Device 2 (UDEF2) Idle Timer Enable. Turn on UDEF2 Idle Timer Count Register (F0 Index A2h) and gener-
ate an SMI when the timer expires.
0: Disable.
1: Enable.
If an access occurs in the programmed address range, the timer is reloaded with the programmed count.
UDEF2 address programming is at F0 Index C4h (base address register) and CDh (control register).
Top level SMI status is reported at F1BAR0+I/O Offset 00h/02h[0].
Second level SMI status is reported at F0 Index 85h/F5h[5].
User Defined Device 1 (UDEF1) Idle Timer Enable. Turn on UDEF1 Idle Timer Count Register (F0 Index A0h) and gener-
ate an SMI when the timer expires.
0: Disable.
1: Enable.
If an access occurs in the programmed address range, the timer is reloaded with the programmed count.
UDEF1 address programming is at F0 Index C0h (base address register) and CCh (control register).
Top level SMI status is reported at F1BAR0+I/O Offset 00h/02h[0].
Second level SMI status is reported at F0 Index 85h/F5h[4].
Keyboard/Mouse Idle Timer Enable. Turn on Keyboard/Mouse Idle Timer Count Register (F0 Index 9Eh) and generate an
SMI when the timer expires.
0: Disable.
1: Enable.
If an access occurs in the address ranges listed below, the timer is reloaded with the programmed count:
Top level SMI status is reported at F1BAR0+I/O Offset 00h/02h[0].
Second level SMI status is reported at F0 Index 85h/F5h[3].
Parallel/Serial Idle Timer Enable. Turn on Parallel/Serial Port Idle Timer Count Register (F0 Index 9Ch) and generate an
SMI when the timer expires.
0: Disable.
1: Enable.
If an access occurs in the address ranges listed below, the timer is reloaded with the programmed count.
Top level SMI status is reported at F1BAR0+I/O Offset 00h/02h[0].
Second level SMI status is reported at F0 Index 85h/F5h[2].
