Note: Please note that the Apple Authentication Coprocessor will not be provided on the
CX module. The Apple Authentication Coprocessor should be provided on the product
motherboard, connected to the SDA, SCL signals from the CX module.
Note: Shaded rows indicate Custom or Obsolete configuration - NOT TO BE USED FOR
NEW/STANDARD MP DESIGNS.
