|23:16||CEL[7:0]||X||0x0||CAN Error Logging|
The counter is incremented each time when a CAN protocol error causes the Transmit Error Counter or the Receive Error Counter to be incremented. It is reset by read access to CEL. The counter stops at 0xFF; the next increment of TEC or REC sets interrupt flag IR.ELO
0 – The Receive Error Counter is below the error passive level of 128
1 – The Receive Error Counter has reached the error passive level of 128
|14:8||REC[6:0]||R||0x0||Actual state of the Receive Error Counter, values between 0 and 127|
|7:0||TEC[7:0]||R||0x0||Actual state of the Transmit Error Counter, values between 0 and 255|
When CCCR.ASM is set, the CAN protocol controller does not increment TEC and REC when a CAN protocol error is detected, but CEL is still incremented.
