1B , CAN Supply under voltage detected. Transmitter disabled
Notes
1. CAN and LIN Recovery Conditions:
1.) TXD Time Out: TXD goes HIGH or transmitter is set to wake capable or switched off;
2.). Bus dominant time out: Bus will become recessive or transceiver is set to wake capable or switched off.
3.) Supply under voltage: as soon as the threshold is crossed again, i.e. VSHS > VS_UV for LIN and VCAN >
VCAN_UV for CAN
4.)In all cases (also for TSD shutdown): to enable the Bus transmission again, TXD needs to be HIGH for a
certain time (transmitter enable time).
2. The VCAN_UV comparator is enabled if the mode bit CAN_1 = â1â, i.e. in CAN Normal or CAN Receive Only
Mode.
3. CANTO will be set only if CAN2 = 1 (=SWK Mode enabled). It will be set as soon as CANSIL was set and will
stay set even in CANSIL it is reset. An interrupt is issued in SBC Stop- and SBC Normal Mode as soon as
CANTO is set and the interrupt is not masked out, i.e. CANTO_MASK must be set to 1.
4. The SYSERR Flag is set in case of a configuration error and in case of an error counter overflow (n>32).
It is only updated if SWK is enabled (CAN_2 = â1â). See also Chapter 5.4.3.
