user39896: I have built a custom Arduino Micro PCB, but I have made a mistake, I accidentally attached an interrupt pin for a Gyro sensor to pin 12 of the Micro, not realizing it wasn't an external interrupt pin.
I tried using the interrupt pin change command found on the Arduino website, but I am having some trouble getting it working. If there is a way to make pin 12 on the Arduino Micro an Interrupt pin, how would I go about doing that in the simplest way.

user30005: 
If there is a way to make pin 12 on the Arduino Micro an Interrupt pin

you should take a look at the device datasheet and see what other functionalities pin 12 has. 
if it is a pcint pin, you are golden;
if it is a timer input pin or an input capture pin, they can be programmed to act like an interrupt pin as well.
all begins with reading the datasheet.
