#CIAA-ACC
3.3V at U36 feeds through to VCCO_HR on the FPGA input pins. Potential solutions include reviewing U36 to find an alternative chip that allows using VCCO_HR as power supply or using a level shifter on the Rx pin. The TI ISO1042 isolated CAN transceiver allows VDD from 1.71V on the FPGA side but needs 5V on the CAN interface side.
