ABSTRACT:
Apparatus and method for a microcontroller are described. The microcontroller includes a microprocessor having storage and bussing for accessing the storage. A portion of the bussing is coupled to hardwired operation codes, and a portion of the storage is for storing code. The hardwired operation codes are in part for placing the microprocessor into an exception handling mode. The exception handling mode includes reactivating the storage for execution of the code without having to reload the code therein.
