• Manufacturer Part Number: si3482
• Description: Power Management Controller
• Manufacturer: Silicon Laboratories

4.9. Events
An event is an unsolicited notification from the Power Manager that a status has changed. The Power Manager
calls the event handler in the Serial Packet Server whenever there is a change in system status, port status, or
power supply status. The Serial Packet Server stores the events in an event queue.
If a User Interface component wishes to receive events, it provides the address of an event handler when it calls
InitPowerManager(). The Serial Packet Client spawns an event task. The event task remotely calls the GetEvents()
routine in the Serial Packet Server every 200 ms to retrieve the events from the event queue. For each event that
is retrieved, the Serial Packet Client calls the event handler in the User Interface component.
4.9.1. GetEvents
