proper number of clock cycles to start an internal write
cycle. Access to the array during an internal write cycle
is ignored and program-ming is continued. On power up,
SO is in a high impedance.

When powering down, the supply should be taken down
to 0V, so that the CAT25C32/64 will be reset when
power is ramped back up. If this is not possible, then,
following a brown-out episode, the CAT25C32/64 can
be reset by refreshing the contents of the Status Regis-
ter (See Application Note AN10).
