TM4C1294NCPDT: Will ISR function pre-empt the faultISR or NmiISR functions?

Hi,

1. What is the priorities of those fault handlers?

2. Where can i learn about fault handlers?

  This is documented in the datasheet. Please refer to the section 2.5 Exception Model in the datasheet. As you can see, a hard fault is an exception that occurs because of an error during exception processing, or because an exception cannot be managed by any other exception mechanism. Hard faults have a fixed priority of -1, meaning they have higher priority than any exception with configurable priority.

No. Other ISRs will have lower priority than fault handlers.
