HS-CAN module mode
00B , CAN OFF
01B , CAN is wake capable
10B , CAN Receive-Only mode
11B , CAN Normal mode
Note: In case CAN transceiver is configured to ‘11’ while going to SBC Stop or Sleep mode, it will be
automatically set to wake capable (‘01’). However, the SPI bits will stay unchanged, i.e. once the SBC
returns to Normal mode, the previous state is recovered again (‘11’). The Receive-Only mode (‘10’) has to
be selected by purpose before entering SBC Stop mode. For more details, refer to Figure 18.
In case of entering SBC Sleep mode, the CAN transceiver has to be set to CAN wake capable or CAN OFF
mode before.
In case LIN transceiver is configured to ‘11’ while going to SBC Stop or Sleep mode, it will be automatically
set to wake capable (‘01’). However, the SPI bits will stay unchanged, i.e. once the SBC returns to Normal
mode, the previous state is recovered again (‘11’).The Receive-Only mode (‘10’) has to be selected by
purpose before entering SBC Stop mode. For more details, refer to Figure 25.
