Functional Description

Undervoltage on the Digital Supply V_IO
If the voltage on V_IO supply input falls below the threshold V_IO < V_IO(U,F), the transceiver TLE7250X powers down
and changes to the power-down state.
The undervoltage detection on the digital supply V_IO has the highest priority and is independent of the transmitter
supply V_CC and also independent of the currently selected operating mode, an undervoltage event on V_IO always
powers down the TLE7250X.
