The SPI lines are connected form the MCU to the SP141 or SP144 (depending which board you're using)
If you want to use an external MCU you can connect them from the UEXT connector or from the Freedom\Arduino connectors (check schematics)
You will need to disconnect the SPI lines from the Freescale's K22 to the SP14X by flipping the switch S8-switch#2. This will prevent contention on the lines.
Hope this helps
Oran
