Figure 2.2 CAN signal secondary function selection resistor
The second function pin of the CAN signal is switched by using R24 (this resistor can
be found on the rear of the board, as shown in Figure 2.2). R24 is welded by default. The
system uses the default on-board CAN transceiver ADM3053. When R24 is removed, the
second function pin of the CAN signal is automatically enabled when the system is
powered on. Table 2.3 lists the pin sequence. At this time, R29 and R30 need to weld 0
ohm resistors to enable CAN0, while R31 and R32 respectively weld 0 ohm resistors to
enable CAN1.
