5.2.5.2
A wake - up via LOW signal on the pin WK is called local Wake - Up. A falling edge of the signal on the pin WK
followed by a LOW signal for the time t >
By Mode. In the case the LOW signal is shorter then the time t <
remains in Sleep Mode or Stop Mode. In Stand-By Mode the wake - up source is indicated by the TxD and RxD
pins (see
Figure 7
5.2.5.3
The EN pin is used for the mode selection. In case the power supply
Mode, the TLE8458Gx can be directly transferred into Normal Operation Mode by setting the EN pin to HIGH. An
integrated pull - down resistor at the EN pin avoids mode changes due to floating signals on the EN input. The
TLE8458Gx changes the operation mode to Normal Operation Mode, from Stop Mode or from Sleep Mode if the
EN pin is HIGH for the time t >
The mode transition via the EN pin will not be indicated in Stand-By Mode.
