The transmitter and receiver cores can be connected together internally to allow for development and debug. This is achieved by setting RX_MAIN_CTRL_ALTC_.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 7-354 shows the signal connections with internal loopback.
