Hello experts,

I was doing some testing on a C1000H recently, and as I was trying to force a bit, I got an error that I have not seen before


This did not affect anything that I was trying to do, (as far as I am aware anyway), but did surprise me all the same.

Could this be platform specific to the C1000H?

What address was the bit? Could it be a special Force all cancel flag?

I just had this happen to me last week while working on a C1000H as well. I'm not positive but I think the C1000H might be able to handle only one force at a time. I think this is why it asks to reset any previously forced bits. Mine will not let me enable more than one force. Not sure if it is a setting or just beyond the limits of this controller.

I was just using CIO areas, trying to override actual IOP for some debugging.




I think that is correct, I am pretty sure that when I forced a new bit, the previous force was still there. I will test this again though.

Perhaps switching to program mode will allow more than one force?

They were basically upgraded C500s and if I remember correcty (long time ago) worked to the same conventions as the C500. If I remember correctly 1 force was it.
