26.17.11 ECC Single Bit Error Code Register (DCAN ECC SERR)

If an ECC single bit error is detected, the SEFLG flag will be set in the ECC Control and Status Register.

In addition to the SEFLG flag, the ECC Single Bit Error Code Register will indicate the memory area

where the single bit error has been detected (message object number only).

If more than one word with an ECC single bit error was detected, the highest word number with an ECC

single bit error error will be displayed.

After an ECC single bit error has been detected, the register will hold the last error code until power is

removed.
