ATA6602/ATA6603
With EN high you can switch directly from Silent mode to Normal mode. In the application where
the LIN-SBC supplies the microcontroller, wake-up from Sleep mode is only possible via LIN or
pin WAKE.
If the device is switched into Sleep mode, VDD ramps down without generating an undervoltage
reset at pin NRES.
