@MaureenHelm rt1060 and rt1050 all pass,but Rt1020 does not.

[MaureenHelm]

I can reproduce this, but I can't explain yet why rt1020 behaves differently from rt1050 and rt1060. According to their respective hardware reference manuals, all three parts have 160 vectors, with the last few vectors reserved. The number of reserved vectors at the end of the table varies by part, with the rt1020 having the most reserved. I suspect that rt1020 may actually have less than 160 vectors, but I need to check with the hardware team.
