I am thinking about using the Error Pin on the Inmos T800 transputer to generate external events from a program(e.g., connecting the error pin of one transputer to the event pin of another). But I am not sure if it is a good idea to do that. In Colin Plumb's Transputer instruction set docu., it says that the error flag will never be set by a correct program and the error flag can be ignored if the hardware is agreeable. Does it mean that normal SIGNED arithmetic will not set the error flag? How to make the hardware "agreeable" if it isn't? I would much appreciate any suggestion from those who have experience and expert knowledge in using either the event pin or error pin of the transputer. I badly need your help. -------------------------------------------------------------------------------- Jie C.
