Operation Modes The TLE 6263 offers four different operation modes that are controlled via the SPI interface (NSTB= SPI Input Bit3, ENT=SPI Input Bit2): the normal operation mode, the receive-only mode, the V the state diagram (figure 3). Normal ...

That allows the total current consumption to drop down to less than 100 µA. When a reset occurs, due to false watchdog triggering, the TLE6263 automatically switches from normal mode or receive-only mode respectively, ...
