3.4.20 FSI Interface

One FSI Interface (1Tx and 1Rx) from SoC is terminated on the 2x5 header with part number 67997-410HLF from Amphenol ICC (FCI) having connections, which can be interfaced to C2000 EVM. FSI_TX0 signals and FSI_RX0 signals are connected to the mux so that the signals are available to both the FSI connector and the expansion connector. The TS3A27518E mux-demux is used for this purpose and is controlled by GPIO from IO Expander. A logic low in Mux select pin connects port A and Port B1, whereas a logic high connects A port to B2 port. The default state of mux drives the signals from A port to B1 port, which is connected to HSE connector.
