Abstract: The microprocessor has a CPU with registers containing a contextual data and a pointer of stack (SP, SPH, SPL). A memory (MEM2) has a stack (STK) for backup of the contextual data. The CPU is arranged to backup the contextual data contained in a variable number of registers according to a flag value stored in a register (CCR, CR) to backup, at a time of shifting from one program to another. An independent claim is also included for a process of management of stack of microprocessor.
