A Physical Bus Error (PBE) has to be detected by a commander, if no valid message can be generated on the bus (bus shorted to GND or VBAT). The bit monitor detects a PBE during the header transmission, if no Synch Break can be generated (for example, because of a bus shortage to VBAT) or if no Synch Break delimiter can be generated (for example, because of a bus shortage to GND). Once the Sync Break Delimiter was validated, all other deviations between the monitored and the sent bit value are flagged as Bit Errors (BE) for this frame.
