Wake Events
Wake events are events that turn power on
(activate nPowerOn output) if enabled. These
events can also be enabled as SMI, SCI and
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
The following are SMI events that are not wake events:
