A METHOD FOR EMULATING A NON-BOND-OUT VERSION OF A MICROCONTROLLER THAT HAS STANDARD PORT MEANS, A MICROCONTROLLER ALLOWING SUCH EMULATING, AND A SYSTEM FOR EXECUTING THE EMULATION
For emulating a non-bond-out version of a microcontroller, a standard port is multiplexed amongst user data and program store addresses. An external register is connected to the port for therein latching program store addresses. The microcontroller is synchronized according to a machine cycle that has a plurality of states which each comprise at least two clock pulses. In particular, the port is used for outputting mutually exclusive parts of a single program store address in contiguous sections of a single machine state for external parallel evaluation.
