title: GPIO Level Triggered Understanding
body: <p>I have recently started working on GPIO Interrupts both edge triggered as well as level triggered. I implemented edge triggered and that seems to be working fine, but for level triggered interrupts, I am a little confuzed.</p>
  
  <p>Suppose, I pull the <strong>pin low for initial state</strong> and configure the pin as <strong>High level triggered Interrupt</strong>. So, if I will now connect Vcc to my pin, I will receive an interrupt. That's fine. My question is now if I keep my Vcc continuously connected to this pin, should the interrupts keep on coming or should it trigger only once?
  Note: I have cleared the pending interrupt in Gpio Handler Interrupt routine.</p>
  
  <p>In case any good reference document is available, please provide the link also, I want to dig deeper into it. Thanks</p>
