Wake - Up Functions

Mode Change via the EN and NSTB pin
Besides a mode change issued by a Wake - Up event, the operation mode on the TLE6251-2G can be changed
by changing the signals on the EN and NSTB pins. Therefore the power supplies V_CC and V_IO have to be active.
According to the mode diagram in Figure 4 the operation mode can be changed directly from Sleep Mode to the
Receive - Only Mode, Normal Operation Mode and to the Go - To - Sleep Command. A change from Sleep Mode
direct to Stand-By Mode is only possible via a Wake - Up event. For example by setting the NSTB pin and the EN
pin to logical “High” the TLE6251-2G changes from Sleep Mode to Normal Operation Mode (see Figure 8).
The pins EN and NSTB have a hysteresis between the logical “Low” and the logical “High” signal in order to avoid
any toggling during the operation mode change.
