SNOOZE MODE
SNOOZE MODE is a low-current, power-down mode in
which the device is deselected and current is reduced to
ISB2Z. The duration of SNOOZE MODE is dictated by the
length of time Z is in a HIGH state. After the device en-
ters SNOOZE MODE, all inputs except ZZ become gated
inputs and are ignored. ZZ is an asynchronous, active
HIGH input that causes the device to enter SNOOZE
MODE.
When ZZ becomes a logic HIGH, ISB2Z is guaranteed af-
ter the setup time tZZ is met. Any READ or WRITE op-
eration pending when the device enters SNOOZE MODE
is not guaranteed to complete successfully. Therefore,
SNOOZE MODE must not be initiated until valid pend-
ing operations are completed.
