It is also possible to combine loopback mode and silent mode by setting bits LBack and Silent at the same time. The CAN hardware can be tested without affecting the CAN network. In this mode, the CAN_RX pin is disconnected from the CAN core and no dominant bits are sent on the CAN_TX pin.
Figure 21-7 shows the connection of the signals CAN_TX and CAN_RX to the CAN Core in case of the combination of loopback mode with silent mode.
