2.9.8.1 MCAN

The AM261x controlSOM does not have any onboard MCAN transceiver. To interface with the AM261x MCAN peripheral, the AM261x controlSOM must be connected to the HSEC180ADAPEVM-AM2 and plugged into the TMDSHSECDOCK-AM263. The TMDSHSECDOCK-AM263 has an onboard 2-channel MCAN transceiver.

Two instances of MCAN are MCAN0 and MCAN1, which are routed to the SOM HD Connectors for interfacing using the HSEC180ADAPEVM-AM2 and TMDSHSECDOCK-AM263 or compatible base board. Both MCAN peripherals can be accessed through the 2-channel MCAN transceiver on the TMDSHSECDOCK-AM263.

There is a single 1:2 Mux that controls the routing of the MCAN1_RX signal, which is muxed with I2C1_SCL. Figure 2-25 shows the MCAN peripheral routing on the AM261x controlSOM.
