Abstract: Microprocessor (MP2) includes a device (CPU) to protect contextual data (CCo,Ao,Xo,PCho,PCIo) in its stack (STK) at the time of a interruption of a test program. A delivery device brings a data (CCo,Ao) present in the stack (STK) to an I/O port of the microprocessor at the beginning of a test session starting at the top of the stack. A pointer of the stack (SP) is decremented by a value corresponding to the number of delivered contextual data. An Independent claim is included for: (a) a method of managing a memory space of the microprocessor after the interruption by a test program for registering context data in a stack
