2.4 Erase
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-
ming cycle, except on ‘93C’ devices where the rising
edge of CLK before the last address bit initiates the
write cycle.
The DO pin indicates the Ready/ Busy status of the
device if CS is brought high after a minimum of 250 ns
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.
Note: Issuing a Start bit and then taking CS low
will clear the Ready/ Busy status from DO.
