ABSTRACT:
A method and apparatus for providing a programmable device with operational parameters applicable to successive operational environments. According to some aspects, the method includes the steps of programming memory with a common operational code applicable to multiple operational environments, programming memory with a first operational environment dependent code, operating said device in a first operational environment, changing to a second operational environment, adding a second operational environment dependent code, and operating in a second operational environment. According to some aspects, the apparatus comprises a programmable device operating according to a set of operational parameters reprogrammably stored therein. The device comprises a memory having a first region containing a common operational code independent of operational environment, a programmable second region containing a first operational environment dependent code, and a programming module coupled to receive an operational environment dependent signal and to provide a programming instruction to the second region.
