Defect of the error signaling lines.
SPI shorted to GND
Defect of the error signaling lines.
INTN shorted to VIO or VCC
TxD line becomes interrupted
TxEN line becomes interrupted
TxEN signal is permanently low
(“babbling idiot”)
BD detects an overtemperature condition
Bus load too low
(i.e. one of two line termination units becomes
disconnected from the channel)
Bus load too high
Undervoltage on VIO
(VCC available)

BD outputs Data_0,
when enabled via
TxEN
(internal pull down
resistor)
BD outputs idle state
to the channel
(internal pull up resis-
tor)
After a timeout
dTOTxEN the BD out-
puts idle state to the
channel
BD outputs idle state
to the channel
Note: Depending on
application commu-
nication will fail or
might continue with
degraded perform-
ance

No detection by BD itself.
Software plausibility
check. Analysis of the SPI
response e.g. 0x0000.
No detection by BD itself.
Software plausibility
check. Comparison of the
INTN level with SPI failure
flags.
No detection by BD itself.
CC error at the receiving
ECU
No detection by BD itself.
CC error at the receiving
ECU
After timeout (dTOTx-
EN ) the BD sets INTN
to ‘low’ and sets the bit
‘TxENLOW’=1 in the SPI
register
INTN changes to LOW
OTEMP=1 in SPI register

BD changes to BD_Stand-
by. No data sending or re-
ceiving possible.
