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 ZZ is in a HIGH state. After the device enters
SNOOZE MODE, all inputs except ZZ become gated in-
puts and a 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 de-
vice enters SNOOZE MODE is not guaranteed to complete
successfully. Therefore, SNOOZE MODE must not be initi-
ated until valid pending operations are completed.
