Figure 9. WAKE Input Pin Behavior

7.12.6 Remote Wake-up

In all low power modes, if the differential voltage on the bus becomes recessive for longer than t_BUS_WR, WAKE_REMOTE rises up. If the

differential voltage on the bus becomes dominant for longer than t_BUS_WR, WAKE_REMOTE falls down as shown in Figure 10.

Figure 10. Remote Wake-up Event

A remote wake request is detected after two dominant pulses with each pulse separated by a recessive pulse of at least Trec (wake). The remote

wake detection circuit is active in Sleep and Standby modes. The wake message pattern is shown in Figure 11.
