CANFD_MCANErrCode_FORM_ERROR	A fixed format part of a received frame has the wrong format.
CANFD_MCANErrCode_ACK_ERROR	The message transmitted by the MCAN was not acknowledged by another node.
CANFD_MCANErrCode_BIT1_ERROR	During the transmission of a message (with the exception of the arbitration field), the device wanted to send a recessive level (bit of logical value 1), but the monitored bus value was dominant.
CANFD_MCANErrCode_BIT0_ERROR	During the transmission of a message (or acknowledge bit, or active error flag, or overload flag), the device wanted 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 CPU to monitor the proceeding of the Bus_Off recovery sequence (indicating the bus is not stuck at dominant or continuously disturbed).
CANFD_MCANErrCode_CRC_ERROR	The CRC check sum of a received message was incorrect. The CRC of an incoming message does not match with the CRC calculated from the received data.
CANFD_MCANErrCode_NO_CHANGE	Any read access to the Protocol Status Register re-initializes the LEC to 7. When the LEC shows the value 7, no CANFD bus event was detected since the last CPU read access to the Protocol Status Register.
