The TS-4800's FPGA contains two SJA1000-compatible CAN controllers. The first CAN controller brings CAN RX and CAN TX signals to the baseboard through CN2 pins 97(TX) and 99(RX). The second CAN controller brings CAN2 RX and TX to CN1, pins 69(RX) and 71(TX). The TSCTL software library is used to access the functionality of the two CAN controllers. See tsctl for the software support of the CAN interface.
