Abstract
In a method of handling errors in a digital system that includes a root complex in data communication with at least one endpoint, the endpoint including at least one advanced error reporting register, an error is detected by the endpoint. Error data indicative of the error is stored in an advanced error reporting register. An indication of which transaction caused the error is stored in a secondary location. An error message packet that includes the error data and the indication of which transaction caused the error is generated. The error message packet is transmitted to the root complex. The root complex is caused to take a preselected action in response to the error message packet.
