GIDE PinIO Dont Generate Other Methods

• Only the NegVal method is used in this course, it
  is recommended to set all the other methods as
  "don't generate code".
  
• Set these values using the same way as the
  previous method was set.

26
GIDE Interrupt Bean

• Now you have inserted the output bean for the LED
  on pin C5 on port C.
