Synchronization jump width (SJW) of bit time segment


SJW displays the synchronization jump width of the bit time segment. To adjust the on-chip bus clock, the controller may shorten or prolong the length of a bit by an integral number of time segments. The maximum value of these bit time adjustments are termed the synchronization jump width or SJW.


This property is not available for National Instruments® CAN devices. The channel displays NaN for the value.
