Write
and the data, the CS (Chip Select) pin must be deselected for
a minimum of t
self clocking clear and data store cycle of the memory
location specified in the instruction. The clocking of the SK
pin is not necessary after the device has entered the self
clocking mode. The ready/busy status of the CAT93C56/57
can be determined by selecting the device and polling the
DO pin. Since this device features Auto−Clear before write,
it is NOT necessary to erase a memory location before it is
written into.

and polling the DO pin. Once cleared, the content of a
cleared location returns to a logical “1” state.
