Title: Method of initializing CPU for emulation

Abstract: A method of initializing a CPU (14) to run emulation code from a debugger (11). Emulation logic (13) associated with the CPU (14) has a finite state machine (13b) with three modes: a reset mode in which no requests from said debugger or said CPU are serviced, a normal mode in which requests from said debugger are given priority, and a start-up mode in which only requests from said debugger are serviced. For initialization, the finite state machine (13b) is placed in reset mode and held in reset while the start-up mode is requested. When the reset mode is released the start-up mode is immediately serviced. This permits an initialization state to be cleanly applied to the CPU (14).
