Interrupts during flash programming

While programming the flash memory cannot provide instructions to the processor for execution. So you can only run programs from cache (which you processor doesn't have) or RAM.

I expect that your code writes a group of data to the flash memory. Then between each write there is a very small time window where the interrupt can fire. and prevent execution of the next flash write (for a short while). That's why the interrupts happen at all...
