flash and interrupts routines from ram

Recently I integrated ROM_FlashErase and ROM_FlashProgram into our application.  Once we integrated them, we started missing a small number of interrupts (0.13%).

I might be missing it, but I don't see anything in the TivaWare manual or the TM4C datasheet that says accessing flash might cause interrupts to be missed or increase their latency.  I now have the problem fixed (0.00% interrupt loss), but I had to move FlashErase, FlashProgram, and our interrupts into RAM.

Can someone at TI please confirm this is in required and if anything else is required.

Many thanks,

JR
