Guess what this code does on a DUE???

void setup() {
 
}
//connect a led from pin 12 (anode) to ground (cathode)
void loop() {
  pinMode(12,OUTPUT);
  
  delay(500);
  
  pinMode(12, INPUT);
  
  delay(500);
  
}

I suspect it does almost the same as your other post but on a different pin? Just a wild guess......
