clear cycle of all memory locations in the device. The
clocking of the SK pin is not necessary after the device has
entered the self clocking mode. The ready/busy status of the
CAT93C66 can be determined by selecting the device and
polling the DO pin. Once cleared, the contents of all memory
bits return to a logical “1” state.
