Normal Mode Application Note

When using the TLIN2029-Q1 in systems which are monitoring the RXD pin for a wake-up request, special care should be taken during the mode transitions. The output of the RXD pin is indeterminate for the transition period between states as the receivers are switched. The application software should not look for an edge on the RXD pin indicating a wake-up request until tMODE_CHANGE. This is shown in Figure 6-15
