A method of operating an integrated circuit may include receiving an update request via an input-Output protocol, such as the Peripheral Interconnect Component Express (PCIe) protocol. The integrated circuit is placed in an update mode when the update request is received. State information is stored in predefined registers on the integrated circuit and configuration data on the integrated circuit may be subsequently updated. An asserted update mode signal is stored in a status register on the integrated circuit to indicate that the integrated circuit is in the update mode. The configuration data may include a core configuration portion and a peripheral configuration portion. When the integrated circuit is in the update mode, only the core configuration is updated while the peripheral configuration portion may be preserved.
