Abstract
A structure and a method for directing execution of instructions are provided in a microprocessor with an on-chip cache memory. In one embodiment, the microprocessor provides a debug mode, which is activated by a signal on a mode pin. In the debug mode, when a signal is received on a second mode pin indicating that an instruction is to be provided on the memory bus is desired, a cache miss is generated at the next instruction fetch. Thus, the processor is forced to fetch the next instruction from main memory. The instruction is then provided on the memory bus as though it is fetched from the main memory in response to the read cycle resulting from the cache miss.
