Abstract
A system and method for triggering interrupt service routines from a main loop are disclosed. The system can be implemented in a computer readable medium that includes logic for: determining if a first flag has been set where the first flag is set in response to a first request for service and the first request for service is associated with a first message having a priority; determining if the first flag is valid including logic for returning to the main loop if the first flag is not valid; identifying the priority of the first message including logic for returning to the main loop; logic for setting a second flag if the priority of the first message is high; enabling a second request for service if the priority of the first message is high; and processing a first interrupt service routine if the priority of the first flag is high.
