LEC2:0Last Error Code (set to 111 on read)
  • 0 No error occurred since LEC has been reset by successful reception or transmission.
  • 1 More than 5 equal bits in a sequence have occurred in a part of a received message where this is not allowed.
  • 2 A fixed format part of a received frame has the wrong format.
  • 3 The message transmitted by the MCAN was not acknowledged by another node.
  • 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.
  • 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 reces
  • 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.
  • 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.
