LPCXpresso v7.2.0 [Build 153] [2014-05-19] & Win8.1 is showing not all SCT registers (LPCOpen1549 Project) :O

The picture shows SCT0 match registers:

MATCH[0] is displayed, MATCH[1] is empty...

Looks like a problem with displaying unions...

Quite a few parts implement an SCT. Can you confirm exactly which part you are using here?

Is there a particular reason why you are using the Expressions view here, rather than the Peripherals View ?

But that aside, can you please confirm the actual Expression you are using here?

Also, it would be worth increasing the value of the option "Array chunk size for variables view" at:

Window - Preferences - LPCXpresso - Disassembly Debug options

from the default 100 to say 250 or 500. And seeing if this helps.

This project is using SCT0 with several MATCH and CAP registers.

I'll ask again : What is the actual expression that you are adding to the Expression view??

So by experimentation, I can see that the Expression in question is simply "LPC_SCT0".

Anyway, I can replicate the behaviour that you are seeing and we will investigate. What I see here is that the first array element that I open gets displayed.

Any further elements that you then open simply display as a blank line - although if you click on the element line (ie the '0', or '1', etc) then the details display within the Expression view will show the union field values correctly.

Naturally, as we did not claim to fix it... (the report was too late to implement any fix in time for the release).
