2.3.5 FSI

One set of GPIOs with available FSI functionality is directly connected to both the BoosterPack connectors as well as the FSI header, J11. To simplify the layout of the LaunchPad, 0-Ω resistors are placed on the signal trace to remove the BoosterPack Connection from the circuit. The mapping between the GPIOs, the resistors, and the FSI signal is listed in Table 5. R46 also connects GPIO33 to S9, which selects the route to the BoosterPack connector or the CAN transceiver.
