Summary:A system and method for concurrent operations in a microcontroller's program memory is provided. In one exemplary embodiment, a microcontroller system is provided that includes a microcontroller, programmable read-only memory (PROM), random access memory (RAM) and a bridge circuit disposed between the PROM and microcontroller. The bridge is adapted with memory-mapped registers to map specific address locations from RAM to PROM, to permit the microcontroller to update PROM while concurrently executing code from RAM. In another exemplary embodiment, the bridge circuitry includes microcontroller reset and RAM enable/disable capabilities to further efficiently manage memory resources.
