18.3.1.1 Remote Wake-up from Sleep Mode

A voltage lower than the LIN pre-wake detection, V_LINL at the LIN_BUS pin, activates the internal LIN receiver, and starts the wake-up detection timer. A falling edge at the LIN_BUS pin, followed by a dominant bus level maintained for a certain period of time (>t_bus), and following a rising edge at the LIN_BUS pin, results in a remote wake-up request and the device switches to Fail-Safe mode. The LIN_INH pin is activated (switches to V_S), and the internal termination resistor is switched on. The remote wake-up request is indicated by a low level at pin LIN_RXD and interrupts the microcontroller.
