Greetings Any Freescale lurkers out there?
The mpc866 manual implies that if the internal core times out an external Transfer Acknowledge bus signal (by exerting the internally generated Transfer Error Acknowledge signal) an exception is generated. I've tried extending the external TA signal well beyond 2040 clock cycles the maximum timeout allows and I see the busses start up again (indicationg that they are no longer waiting) but I don't see anything on TEA and I don't get an exception thrown. Any clues? Manual error?, silicon error?, my brain error?
