3.3.5 SPI Routing

On the LaunchPad, one set of F2800137 SPI signals are able to be routed to either site 1 or site 2, or both sites for cases using multiple boosterpacks with the SPI. The signal connections are able to be completed by populating 0-ohm resistors on the board. By default, the resistors are populated so that the SPI signals only go to the site 1 boosterpack headers. See the SPI Routing section of the LaunchPad's schematic to see the corresponding resistor circuitry.
