A falling edge at the LIN pin followed by a dominant bus level maintained for a certain time period (> tbus) and followed by a

rising edge at the LIN pin (see Figure 3-4) result in a remote wake-up request. The device switches from silent mode to

fail-safe mode. The remote wake-up request is indicated by a low level at the RXD pin to interrupt the microcontroller (see

Figure 3-4). EN high can be used to switch directly to normal mode.
