Note:
Phase three: “resuming to normal mode”
The sequence for re-entering in normal mode is showed in the following table and diagram:
Figure 17. Resuming to normal mode timing diagram
For proper device operation the “Entering in detection” sequence must be follow by a
“resume mode” sequence, it is not possible to insert consecutive equal sequence.
