The error counter register is a 16-bit read-only register composed of the transmit error counter
(TEC) and receive error counter (REC).
TEC is an 8-bit register that functions as a counter indicating the number of transmit message
errors on the CAN bus. The count value is stipulated in the CAN protocol.
REC is an 8-bit register that functions as a counter indicating the number of receive message
errors on the CAN bus. The count value is stipulated in the CAN protocol.
