An electronic warfare (EW) devices and a method of providing jamming techniques are generally described. Firmware is updated by eliminating an existing jamming technique, adding a new technique and/or changing parameters of one of the techniques in the firmware. Changing the technique parameters includes adding a new parameter, deleting an existing parameter, changing the range of values for an existing parameter and changing the order of the parameters to be transmitted by an Operational Flight Program (OFP) to the firmware to generate the technique. The OFP reads a published a register mapping specifying parameters to use in generating the jamming techniques in the EW firmware, a range of the parameters and an order of the parameters. The jamming techniques are generated using parameters transmitted by the OFP to the firmware. The same OFP is used to trigger generation of jamming techniques prior to and after the updating of the firmware.
