bus lines is affected by a bus line failure) the EME performance of the system is
degraded from the differential mode.

There are 9 different CAN bus wiring failures defined by the ISO 11519-2/ISO 11898-3
standard. These failures are devided into 7 failure groups (see Table 4). The difference
between ISO11898-3 and ISO 11519-2 is also shown in Table 4. When a bus wiring
failure is detected the device automatically switches to a dedicated CANH or CANL
single-wire mode to maintain the communication if necessary. Therefore it is equipped
with one differential receiver and four single ended comparators (two for each bus line).
To avoid false triggering by external RF influences, the single wire modes are activated
after a certain delay time. As soon as the bus failure disappears the transceiver switches
back to differential mode after another time delay.
The differential receiver threshold is set to typ. -2.5V. This ensures correct reception in
the normal operation mode as well as in the failure cases 1, 2, 3a(6a) and 4(5) with a
noise margin as high as possible. When one of the bus failures 3(6), 5(4), 6(3), 6a(3a),
and 7 is detected, the defective bus wire is disabled by switching off the affected bus
termination and output stage. The failure cases in brackets() are the failure cases
according to ISO 11898-3. Simultaneously the multiplexing output of the receiver circuit
is switched to the unaffected single ended comparator
The bus failures are monitored via the diagnosis protocoll of the SPI. Therefore it is
possible to distinguish 6 CAN bus failures or failure groups on the SPI output bits 8 to 13
(see Table 4 and 5). The failures are reported until transmission of the next CAN word
begins.
