Working support for Interconnect - Supports up to 255 slave nodes (you'll run into ScanCode limitations before then) - Requires most recent kll compiler update - Additional debugging output and stats counters - Noise and parity checking - Fixed TxFIFO issue when sending buffers larger than the FIFO - Cleaned up defaultMap.kll - Added ScanCode caching (reduces interconnect traffic significantly) - Interconnect module code is conditionally compiled into PartialMap module if required
