The transmitter and receiver cores can be connected together internally to allow for development and debug. This is achieved by setting RX_MAIN_CTRL.INT_LOOPBACK to 1. Internal loopback routes the signals from the corresponding transmitter to the appropriate receiver pin. No configuration needs to be done in the transmitter. Figure 27-9 shows the signal connections with internal loopback.
In this device, there are two FSI transmitter cores (A and B), and four receiver cores (A, B, C, and D). When using loopback mode, FSITXA can be used in loopback mode with FSIRXA and FSIRXC. At the same time, FSITXB can be used in loopback mode with FSIRXB and FSIRXD.
