TEC can be written to only in test mode (TCR.TSTMD = 1 and TCR.WREC = 1). The
same value should be written to TEC and REC.
REC can be written to only in test mode (TCR.TSTMD = 1 and TCR.WREC = 1). The
same value should be written to TEC and REC.

Description
TEC functions as a counter indicating the number of
transmit message errors on the CAN bus. The count
value is stipulated in the CAN protocol. In normal
operation, TEC can only be read, but can only be
modified by the CDLC. TEC is cleared to 0 by a reset
request (MCR.RSTRQ = 1) or on entering the bus off
state.
TEC can be written to in test mode (TCR.TSTMD = 1 and
TCR.WREC = 1). The same value can be written to both
TEC and REC. TEC should be written to in halt mode. In
other modes, a CAN bus communication error may occur
depending on the TEC value. Note that TEC can be
written to only in test mode.

receive message errors on the CAN bus. The count value
is stipulated in the CAN protocol. In normal operation,
REC can only be read, but can only be modified by the

(MCR.RSTRQ = 1) or on entering the bus off state.
REC can be written to in test mode (TCR.TSTMD = 1 and
TCR.WREC = 1). The same value can be written to both
TEC and REC. REC should be written to in halt mode. In
other modes, a CAN bus communication error may occur
depending on the REC value. Note that REC can be
written to only in test mode.
