Pierce Oscillator - Cap values for XTAL

I'm an HC11 refugee, and am getting ready to test my first 9S12 design.

I'm a little confused about the value of the crystal load caps.

The Abracon crystal spec says 18pF, so I ordered 11pF caps, to take into account the given 7 pF at the EXTAL and XTAL pins.

Is this correct?
