20 amp outlet on 15 amp circuit

I was wondering if it matters putting a single 20 amp outlet on a 15 amp circuit? The outlet is for a microwave hood above our stove. I had to put an outlet in the cabinet above. The circuit is tied to our kitchen/dining room lighting/outlets. The microwave will work on a 15 or 20 amp circuit. I bought a 20 amp outlet just in case and found that the circuit is 15 amps.

To comply with the electtric code you should install a fifteen ampere receptacle. Twenty ampere receptacles should only be installed on twenty ampere circuits.

A 20 amp receptacle(with one slot horizontal) is NOT allowed to be installed on a 15 amp circuit. If you try to run a 20 amp device on a 15amp circuit you will be forever blowing breakers.
