Note 2.
Transition time from STOP mode to SNOOZE mode
Note 3.
Transition time from SNOOZE mode to normal operation
Note 4.
Enable the SNOOZE mode (AWC = 1 or SWC = 1) immediately before switching to the STOP mode.
Note 5.
Be sure to release the SNOOZE mode (AWC = 0 or SWC = 0) immediately after return to the normal operation.
