Wake Events
nPME events as shown in the following table. In
addition, these wake events set the WAK_STS
bit if enabled (see ACPI PM1_STS2 Register
description).
Wake events are events that turn power on
(activate nPowerOn output) if enabled. These
events can also be enabled as SMI, SCI and
INPUT TO SOFT POWER

SIGNALS
Note 1: These SCI/PME events are SMI events that are enabled through DEVINT_EN.
Note 2: These SCI events have Status and Enable bits in the PM1 registers.
Note 3: The polarity of the edge that causes the event is programmable through the polarity bit in the
GPIO configuration registers. The default is the low-to-high edge.
The following are SMI events that are not wake events:
•
•
•
•
Floppy Interrupt
Parallel Port Interrupt
WDT
P12
Any wakeup logic that affects the configuration of the wakeup events is implemented so that the
configuration of the wakeup events is retained (in the event of total power loss) upon Vtr POR.
