title: Where to find I bit and how to edit it to enable interrupts in ARM Cortex-M4
body: <p>In ARM Cortex-M4F MCU (TM4C1294NCPDT specifically), to deal with interrupts (GPIO interrupts), one of the steps to get the interrupts working is to clear the I BIT.</p>
  
  <p>I searched a lot but I couldn't find any useful information about that, could anybody please tell me where to find that bit exactly and how to edit it if I need some special procedures?</p>
  
  <p>And that will be great if I have been told where to find that information exactly after the explanation please (to learn how to answer myself on any other questions).</p>
