(1) ISUP(BIAS) is calculated by subtracting the supply current in CAN autonomous inactive mode from the total supply current in CAN autonomous active mode
(2) After a valid wake-up, the CAN transceiver switches to CAN autonomous active mode and the ISUP(BIAS) current needs to be added to the specified ISUP current in CAN autonomous inactive mode.
