7.3 Phase three: “resuming to normal mode”
The sequence for re-entering in normal mode is showed in the following table and diagram:
Note: 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.
