Cortex Architecture Register Usage

I some questions regarding the new VEX Cortex Microcontroller.
This information was available for the original VEX v 0.5 Microcontroller. Any help regarding this subject would be greatly appreciated.

  1. How are the VEX Digital, Analog and Interrupt ports mapped to the Cortex MCU?
  2. Which ports are the fast digital ports?
  3. What I/O ports use weak pull-ups, inline resistors and diodes which could affect hardware connected to the Cortex?
