Last Error Code (set to 111 on read)

Value on reset: 0

Variants

NO_ERROR

0: No error occurred since LEC has been reset by successful reception or transmission.

STUFF_ERROR

1: More than 5 equal bits in a sequence have occurred in a part of a received message where this is not allowed.

FORM_ERROR

2: A fixed format part of a received frame has the wrong format.

ACK_ERROR

3: The message transmitted by the MCAN was not acknowledged by another node.

BIT1_ERROR

4: During transmission of a message (with the exception of the arbitration field), the device tried to send a recessive level (bit of logical value '1'), but the monitored bus value was dominant.

BIT0_ERROR

5: During transmission of a message (or acknowledge bit, or active error flag, or overload flag), the device tried to send a dominant level (data or identifier bit logical value '0'), but the monitored bus value was recessive. During Bus_Off recovery, this status is set each time a sequence of 11 recessive bits has been monitored. This enables the processor to monitor the proceeding of the Bus_Off recovery sequence (indicating the bus is not stuck at dominant or continuously disturbed).

CRC_ERROR

6: The CRC check sum of a received message was incorrect. The CRC of an incoming message does not match the CRC calculated from the received data.

NO_CHANGE

7: Any read access to the Protocol Status Register re-initializes the LEC to '7'. When the LEC shows value '7', no CAN bus event was detected since the last processor read access to the Protocol Status Register.
