• CAN bus errors (stuff error, form error, ACK error, CRC error, bit error, and ACK
delimiter error) can be monitored.
• Transition to error states can be detected (error-warning, error-passive, bus-off
entry, and bus-off recovery).
• The error counters can be read.
Time stamp function using a 16-bit counter
The reference clock can be selected from either 1-, 2-, 4- or 8-bit time periods.
6 types:
• Reception complete
• Transmission complete
• Receive FIFO
• Transmit FIFO
• Error
• Wake-up
Current consumption can be reduced by stopping the CAN clock.
3 software support units:
• Acceptance filter support
• Mailbox search support (receive mailbox search, transmit mailbox search, and
message lost search)
• Channel search support
Selectable BCLK or main clock
3 test modes available for user evaluation:
• Listen-only mode
