10-8. Sector Erase (SE)
Sector Erase is an operation that sets the memory cell data in any sector to "1". A sector consists of 64Kbytes.
"Figure 11. Sector Erase (SE)" shows the timing waveforms.
"Figure 33. Sector Erase Flowcharts" shows the flowcharts.
The sequence of SE operation :
CS goes to low  input SE command (D8h)  3 Byte address (A23-A0) input on SI
 CS goes to high (be executed by the rising CS edge)
* A20 to A16 are valid address
After the correct input sequence the internal erase operation is executed by the rising CS edge, and it is completed
automatically by the control e xerc ised by the internal time r (tSE). The end of e rase operation can also be detected by
status register (RDY).
