TLE6251DS. If the dominant signal switches back to recessive level, e.g. failure removed, a
wake-up via CAN bus (recessive to dominant signal detected) is possible.
Figure 5
Wake-up via CAN Message
During standby mode, a dominant CAN message on the bus longer than the filtering time
leads to the activation of the wake-up. The wake-up during standby mode is signaled with the
RxD output pin. A dominant signal longer
LOW, with a following recessive signal on the CAN bus longer
to high, see
The µC is able to detect this change at RxD and switch the transceiver into the normal mode.
