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 enters
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 after
the setup time tZZ is met. Any READ or WRITE operation
pending when the device enters SNOOZE MODE is not
guaranteed to complete successfully. Therefore, SNOOZE
MODE must not be initiated until valid pending operations
are completed.
