The F28004x TRM sprui33c mentions a NMI source called PIEVECTERR (PIE vector error). Page 457 gives the only description of this I can find:
PIE Vector Fetch Error NMI Flag
This bit indicates whether a mismatch was detected during an
interrupt vector fetch. It can be cleared by a system reset or by
writing to the corresponding bit in the NMIFLGCLR register.
Reset type: SYSRSn
0h (R/W) = No vector fetch error detected
1h (R/W) = Vector fetch error detected
But this doesn't really say what causes this error. What exactly is a vector fetch error?
