Phase three: resuming normal mode
The sequence for reentering normal mode is shown in the following table:
Figure 21. Resuming normal mode - timing diagram
For proper device operation, the “entering error detection” sequence must be followed by a
“resume mode” sequence, it is not possible to insert consecutive equal sequences.
