7.2
If a local failure occurs during the operation of the TLE6251-3G, 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
out feature and the TLE6251-3G disables the output driver stage. In Receive-Only mode the TLE6251-3G
indicates the TxD time-out by a logical “Low” signal on the NERR pin (see
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.
