Type Description
rwh Receive Error Counter
Bitfield REC contains the value of the receive error
counter for the corresponding node.
rwh Transmit Error Counter
Bitfield TEC contains the value of the transmit error
counter for the corresponding node.
rw Error Warning Level
Bitfield EWRNLVL defines the threshold value
(warning level, default 60_H = 96_D) to be reached in
order to set the corresponding error warning bit
EWRN.
