Methods and structure are provided for trapping incoming requests directed to hardware registers of an electronic device. The electronic device that comprises a set of hardware registers that define a configuration of the electronic device, circuitry that implements programmable logic defining which hardware registers have been flagged for trapping incoming requests, and a shadow memory that includes values corresponding to the flagged hardware registers. The circuitry is further operable to access a value in shadow memory that corresponds to a flagged hardware register, responsive to receiving a request from an external device to access the flagged hardware register. |
