5.4.4.2 SBC Stop Mode with SWK
In SBC Stop Mode the CAN Transceiver can be operated with the following CAN Modes
• CAN OFF
• CAN WK Mode (no SWK)
• CAN SWK Mode
• CAN Receive Only (no SWK)
To enable CAN SWK Mode the CAN has to be switched to “CAN Normal Mode with SWK”, “CAN Receive Only
Mode with SWK” or to “CAN SWK Mode” in SBC Normal Mode before sending the SBC to SBC Stop Mode. The
bit SYSERR = ‘0’ indicates that the SWK function is enabled. The table shows the change of CAN Mode when
switching from SBC Normal Mode to SBC Stop Mode.
Note: CAN Receive Only Mode in SBC Stop Mode is implemented to also enable pretended networking (Partial
networking done in the microcontroller).

Note: When SYSERR is set then WUF frames will not be detected, i.e. the selective wake function is not activated
(no SWK), but the MSB of CAN mode is not changed in the register.
