Fault / Warning
Pre-warning
Refer to descriptions of CANH and CANL short to GND, VDD, and VSUP elsewhere in table.
Peak current 150mA during TXD dominant only. Due to loss of communication, CAN controller reaches bus OFF state. Average current
out of V2 is below 10mA.
Over-current might be detected. THERM-CUR bit set in CAN register.
