Five different operation modes are available on TLE6251-3G. Each mode with specific characteristics in terms of
quiescent current, data transmission or failure diagnostic. For the mode selection the digital input pins EN and
NSTB are used. Both digital input pins are event triggered.
depending on the status of the EN and NSTB pins. A mode change via the mode selections pins EN and NSTB is
only possible if the power supplies
