The CiEFR register determines an error source when a CAN bus error occurs. Set each bit in the CiEFR register
to 0 after reading the CiEFR register by a program.
Use the MOV instruction to set each bit in the CiEFR register to 0. Write a 0 to the bit which is to set to 0, and
write a 1 to the bit which is to remain unchanged.
The ACKE bit becomes 1 when an ACK error is detected.
The CRC bit becomes 1 when a CRC error is detected.
NOTES:
1. The value is obtained by setting the SLEEP bit in the CiSLPR register to 1 (sleep mode exited) after reset and supplying the
2. Set each bit to 0 by a program. Writing a 1 has no effect.
