5.4 Idle Sequence

If the total sequence of required commands exceeds t_WATCHDOG, then the device will automatically go to sleep and lose any information stored in the volatile registers. This action can be prevented by putting the device into Idle mode prior to completion of the watchdog interval. When the device receives the Wake token, it will then restart the Watchdog Timer and execution can be continued.

The idle sequence consists of the proper device address followed by the value of 0x02 as the word address followed by a Stop condition. It can be sent to the device at any time when it is awake and not busy.
