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:
After the Erase cycle is complete, issuing
a Start bit and then taking CS low will clear
the Ready/Busy status from DO.
