APPLICATION NOTES:
• POPUPS AND BACKGROUND HANDLERS
Popup requests are generated when a timer countdown/up expires. Along with the popup request,
the resource will execute the application’s background handler. In due time, the kernel will
execute the application popup. This allows an application to keep on updating the timer resource
with new countdown data even if popups are currently suspended by the system. For example: a
timer application having multiple countdown data that is started in sequence. When the first
countdown data expires, the application resource handler will load the new countdown data and
starts the timer resource.
• PRE-WARNING POPUP
