Fault tolerant CAN transceiver standard modes
known from MC33388.
Table 15. CAN Transceiver Modes
Table 16. CAN transceiver extended modes (CAN with CEXT bit =1 is not recommended)
During read out L0 must be at high level and should stay high when entering sleep or stop.

FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
The CAN transceiver standard mode can be programmed by setting CEXT to 0. The transceiver cell will then be behave as
Fault tolerant CAN transceiver extended modes
By setting CEXT to 1 the transceiver cell supports sub bus communication
Note1: CEXT Bit should be set at 0. The CAN operation in extended mode is not recommended.
Note: if DFIS bit is set to 1, WUR register must be read before going into sleep or stop mode in order to clear the wake-up flag.
