Notes
1. The reset values for the CAN transceivers are marked with ‘y’ because they will vary depending on the cause
of change - see below.
2. see Figure 31 for detailed state changes of CAN Transceiver for different SBC modes.
3. The bit CAN_2 is not modified by the SBC but can only be changed by the user. Therefore, the access type is
‘rw’ compared to bits CAN_0 and CAN_1.
4. In case SYSERR = 0 and the CAN transceiver is configured to ‘x11’ while going to SBC Sleep Mode, it will be
automatically set to wake capable (‘x01’). The SPI bits will be changed to wake capable. If configured to ‘x10’
and SBC Sleep Mode is entered, then the transceiver is set to wake capable, while it will stay in Receive Only
Mode when it had been configured to ‘x10’ when going to SBC Stop Mode. If it had been configured to wake
capable or OFF then the mode will remain unchanged.The Receive Only Mode has to be selected by the user
before entering SBC Stop Mode. Please refer to Chapter 5.4.4 for detailed information on the Selective Wake
mode changes.
5. Failure Handling Mechanism: When the device enters Fail-Safe Mode due to a failure (TSD2, WD-Failure,...),
then the wake registers BUS_CTRL_1 and WK_CTRL_2 are reset to following values (=wake sources) ‘xxx0
1001’, ‘0000 0001’ and ‘x0xx 0111’ in order to ensure that the device can be woken again.
