Abstract

A CAN communication line is operated whilst detecting a ground level shift on the communication line through storing a data element indicative for the shift. In particular, a current line voltage level is compared to a standard level, and a thresholded version of the comparison is fed to a storage element that is triggered by a local transmission indicator signal. Then a ground shift sample bit from the storage element is outputted.
