ATA6622C 数据手册

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

rising edge at the LIN pin (see Figure 4-3 on page 9) results 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 4-3 on page 9). EN high can be used to switch directly to Normal Mode.
