7.9. Sector Erase (SE) (20H)
The Sector Erase (SE) command is for erasing the all data of the specific sector. A Write Enable (WREN) command
must previously have been executed to set the Write Enable Latch (WEL) bit. The Sector Erase (SE) command is entered
by driving CS# low, followed by the command code, and 3-address byte on SI. Any address inside the sector is a valid
address for the Sector Erase (SE) command. CS# must be driven low for the entire duration of the sequence.
The Sector Erase command sequence: CS# goes low  sending Sector Erase command  3-byte address on SI 
CS# goes high. The command sequence is shown in Figure9. CS# must be driven high after the eighth bit of the last address
byte has been latched in; otherwise the Sector Erase (SE) command is not executed. As soon as CS# is driven high, the
self-timed Sector Erase cycle (whose duration is tSE) is initiated. While the Sector Erase cycle is in progress, the Status
Register is accessed to check the value of the Write In Progress (WIP) bit. The Write In Progress (WIP) bit is 1 during the
self-timed Sector Erase cycle, and becomes 0 when it is completed. At some unspecified time before the cycle is completed,
the Write Enable Latch (WEL) bit is reset. A Sector Erase (SE) command applied to a sector which is protected by the Block
Protect (BP2, BP1, BP0) bit (see Table1) is not executed.
