S12 / MagniV MicrocontrollersのトピックMultiple CAN buses on the same S12 MCU https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Multiple-CAN-buses-on-the-same-S12-MCU/m-p/174251#M6029 <HTML><HEAD></HEAD><BODY><P>Hi all,</P><P>&nbsp;</P><P>May sound an easy question to some of you, but I am just wondering if it is possible to have more than 1 physical CAN bus on the same MCU, let's say the S12XS256. I think there are 5 CAN TX/RX port on the S12XS256, but I just don't know how to control all 5 separated physical CAN buses from the same main program of the single S12XS256 MCU. I tried to search for those info on the web but failed to find anything useful.
