Good day I with my MCB517AC Evualuation board at haven Port1 a built driver for a stepping motor attached, as I the board switched on flashed all LEDS in the clock and it gave a clay/tone, which should not it! I white not whether this the indication of a short-circuit or otherwise which was. To this incident I could load no more program on the board, it always came the error message: *** MONITOR ERROR: NO CODE MEMORY RK ADDRESS FFFFH I loaded the EEPROM against with the monitor program. Also I replaced several further elements(too the processor) on the board. But without success. What do I have to do around the problem to repair? Thank you for your efforts (Sorry for my bad english:-)) Yours sincerely Christian Helbling
