1. An apparatus for customization of a protective device, said apparatus comprising: a microprocessor for processing logic schemes associated with protection of power system elements, said microprocessor configured to have select operating intervals; fixed memory coupled to the microprocessor and defining some of the logic schemes for processing by said microprocessor; and programmer programmable memory coupled directly to said microprocessor and modifiable by only a programmer of the protective device, said programmer programmable memory including code space having a compiled settings structure including a plurality of allocation fields, wherein one of the allocation field includes portions of executable code and at least some of the other allocation fields are pointer allocation fields, each being associated with one of the microprocessor operating intervals, wherein each portion of executable code is associated with a select logic scheme to be processed by said microprocessor and wherein each portion of executable code is further associated with one of the pointer allocation fields for specifying the operating interval at which the portion of executable code is to be executed by the microprocessor such that the fixed memory does not require modification during customization of the apparatus.
