Erase
The DO pin indicates the Ready/ Busy status of the
device if CS is brought high after a minimum of 250 ns
The ERASE instruction forces all data bits of the speci-
fied address to the logical ‘ 1 ’ state. CS is brought low
following the loading of the last address bit. This falling
edge of the CS pin initiates the self-timed program-
low (T CSL ). DO at logical ‘ 0 ’ indicates that programming
is still in progress. DO at logical ‘ 1 ’ indicates that the
register at the specified address has been erased and
the device is ready for another instruction.

edge of CLK before the last address bit initiates the

After the Erase cycle is complete, issuing
a Start bit and then taking CS low will clear
