CnLEC - CANn module last error information register
The CnLEC register provides the error information of the CAN protocol.
Notes: 1.
The contents of the CnLEC register are not cleared when the CAN module changes from an
operation mode to the initialization mode.
2.
If an attempt is made to write a value other than 00H to the CnLEC register by software, the
access is ignored.
After reset: 00H
