Two instances of the AM261x MCAN peripheral are routed from the AM261x controlSOM through the SOM HD connectors to the HSEC180ADAPEVM-AM2. On the SOM to HSEC adapter board, the signals are routed directly to the HSEC connector. When docking the controlSOM + SOM to HSEC adapter with the TMDSHSECDOCK-AM263, the HSEC pins with the MCAN0 and MCAN1 signals connect to a 2-channel MCAN PHY (TCAN1046) on the AM26x HSEC docking station.
GPIO43 (EPWM0_A) and GPIO49 (EPWM3_A) are used as standby control signals for each channel of the TCAN1046, and are appropriately routed to the correct HSEC pin to connect to the STB[2:1] pins of the TCAN1046 on the AM26x HSEC docking station.
From the MCAN PHY, The low and high level CAN bus I/O lines for each channel are terminated to a three pin header.
For more information on the implementation of the TCAN1046 on the TMDSHSECDOCK-AM263, see the the MCAN section in the TMDSHSECDOCK-AM263 User's Guide.
