I'm using MPC5746.

I met "Instuction Storage Interrupt (offset 0x30)" when the devince is in the high temperature.

The reference menual describes as below 

"An Instruction Storage interrupt (ISI) occurs when no higher priority exception exists and an Execute Access Control exception occurs."

Please let me know "Execute Access Control exception" and what can case this exception.

Thank you.

“Access control” is related to SMPU core exceptions that can lead in IVOR1/2/3 according table below:

I don't see any relationship with the temperature, if it is, then probably only random.
