Receive error counter
Transmit error counter
State
+1
No change
Receive node has detected an error
(excluding bit errors within the active error flag or
overload flag)
+8
No change
Receive node detects "dominant" after error flag output
of error frame
No change
+8
Transmit node transmits error flag
[when error counter = 0]
(1) Error passive state and Ack error detected, but
"dominant" not detected in passive error flag output
(2) Stuff error occurred during arbitration field
No change
+8
Bit error detected in output of active error flag, overload flag
(error active transmit node)
+8
No change
Bit error detected in output of active error flag, overload flag
(error active receive node)
+8
Each node detects 14 consecutive "recessive" bits from the
beginning of the active error flag or overload flag, and 8
consecutive "dominant" bits detected thereafter
Each node detects 8 consecutive "dominant" bits after the
passive error flag
No change
–1
(±0 when error counter = 0)
Transmit node completes transmission without errors
(1) –1
(1 REC 127)
(2) ±0 (REC = 0)
(3) Set to 127
No change
Receive node completes reception without errors
*
REC: Receive Error Counter
(c) Bit error occurring during intermission
Overload frame is generated.
Note) When an error has occured, error control is performed by the error counter at that time.
After an error flag is output, the indicated values are added to the error counter.
