ABSTRACT:
A processor executes a system call instruction. The processor includes at least two registers in which target addresses may be stored, and selects the target address from one of the registers responsive to the operating mode. Different target addresses may be programmed into the registers, and thus the operating mode of the code sequence may be indicated by which target address is selected.
