Andy, Thanks for that. Do you use an emulator of any sort? I am coming around to thinking it must be a bug in the bondout, or possibly my emulator, although I can't see how the emulator could influence things when it's running at full speed. I have arranged my source to conditionally build with or without the code to match IRP and RP1 depending on the target. The real silicon SEEMS to be fine without the extra code. -- Alan Hall, Ipswich, UK
