7.2
If a local failure occurs during the operation of the TLE6251-2G, the devices sets an internal local failure flag. The
local failure flag can be displayed to the microcontroller during the Receive - Only Mode and the failures are
indicated by a logical “Low” signal on the NERR pin. The following local failures can be detected:
•
•
•
•
•
7.2.1
The TxD Time - out feature protects the CAN bus against permanent blocking in case the logical signal on the TxD
pin is continuously “Low”.
In Normal Operation Mode, a logical “Low” signal on the TxD input pin for the time t > t
Time - Out feature and the TLE6251-2G disables the output driver stage. In Receive - Only Mode the
TLE6251-2G indicates the TxD Time-out by a logical “Low” signal on the NERR pin (see
the output driver stage after the permanent “Low” signal on the TxD input pin disappears, a mode change from
Receive - Only Mode to Normal Operation Mode is required.
